As part of an interview for a research position, three applicants are asked to transfer 150 ?L of distilled water with a P-200 micropipette to a weighing paper and to determine the weight of each drop with an analytical balance. The three measurements made by each of the applicants are listed below.

Applicant A: 0.161 g, 0.147 g, 0.142 g
Applicant B: 0.158 g, 0.156 g, 0.157 g
Applicant C: 0.143 g, 0.153 g, 0.150 g

Q1. Calculate and type in the mean and standard deviation of the measurements by each applicant.
Q2. Calculate applicants' accuracy of micropipetting, and rank the applicants by accuracy.
(A (accuracy) = 100 x Vavg/V0, where A is the accuracy of the pipette, Vavg is the average calculated volume and V0 is the value you set the pipette to dispense. Accuracy should be between 99-101%)
Q3. Rank the applicants by their precision of micropipetting.
Q4 .Select one of the applicants based on 2. and 3., and explain your selection.



This problem asks us to create graphs that represent flights between cities and then identify what type of graphs those are as a result of how they look. So, um, where I started with this was summarizing the given information, so I just kind of made myself a visual to the side. The way I set this up shows that there's four flights from Boston to New York to flights from New York to Boston and so forth. So there's lots of ways you could do that. But having that kind of summarized out to the side is gonna help me a lot. I also went ahead and already set up. All of my Vergis is. So when you're doing that, something you might want to think about when you're strategizing is thinking about what City has the most connections to the others. In this case, that's Newark. So I kinda situated that in the middle to help me have space. Most of all, a Z. I'm looking to connect those as we go through each part of this. There's subtle differences, and so you wanna be looking for keywords in the problem. Andi, as I went through those I just kind of summarized each also, so hopefully that'll help us as we go. Um, but let's go and start with a For part A. We wanted an edge between cities that have a flight between them in either direction was kind of a keyword there, telling us that direction does not matter on DSO. We want to connect each pair of cities that have flights between them, and this will be really simple. We see that Boston and New York have one on and New York and Miami, American, Detroit, American Washington and then Miami in Washington. So that's all we have to do for that one. As you're looking into the table to help you classify, we can notice that this is an undirected graph. It didn't matter what direction these were going in. It doesn't have multiple edges between Verdecia because we were just looking toe show the pair's and there's no loops. So this is a simple graph moving on to Part B. We want an edge in this case for each flight in either direction. So again, direction is not going to matter. This will be an undirected graph, but this time we want an edge, representing each flight. So each flight is definitely key. Word here, as I'm looking kind of to my summarized information over here, I know that there's going to be six total flights between Boston and Newark, 5 35 and one between each of those pairs of cities. And so I'm just trying to fit in six edges between Boston and work, which might be a tight squeeze. But we're going to do our best. Um, something that you want to keep in mind is your drawing these in, though, is that you do wanna leave space between each of the edges so that you can tell that there are multiple lines there. So that is five total between your work and Detroit's three right American Washington's five, then my me Washington just has one, um, again try to make. This is Nida's you can. But at the end of the day, you need to have the total number of flights between each city that number of artists, there's of edges. Excuse me. So we're looking Thio. Identify this. We have an undirected graph, but this time we have multiple edges between the verdict sees we still don't have any loops. And so this one is called a multi crap multi graph. Mhm. Yeah. So as we go forward curtsy had the exact same scenario is part beaded. Except now we're adding a sightseeing loop around Miami. So I'm just gonna drawing that I had on the last slide a little bit quicker this time. We're trying to you need them. So, six between New York and Boston, you need five here for me. Mind not one. Oops. That one between Miami and Washington Still, But now we're adding in a loop. And, of course, on a graph that just looks like a school. So something like that. Um, So we have the same scenario we're looking to classify again to undirected multiple edges between the verdict sees. But this time we do have loops. And so this one we will classify as a pseudo graph again. I'm using kind of the parameters that are given in that table for each of those so you can look it, um, those help you as you're classifying Part D says, um, in essence, that we need an edge from each origin city to each destination city. Um and so the key here is that direction does matter because it's telling us where we need to start and where we need to finish. Also, it doesn't say that we need one for each flight, though, So that's, um, telling us that we're not needing multiple edges like showing each flight. So as I'm looking to my summarized information, I know that there's flights from Boston to New York, so I need to show that on. We put these arrows in to show the direction, and then there's flights from New York to Boston. Mhm on. But of course there is. In the opposite direction is, um, same thing New York and Miami. They have flights in either direction. Same current Eric in Detroit, American Washington. Try your best to show what? Chinese air pointing also. Mhm. And last but not least, we have this one from Washington to Miami. Okay, you in Alright. So that's representing kind of all of the pairs again of origins and destinations this time. So, as we look to classify, we have directed graph because we included those arrows. Has, um it looks like multiple edges, so don't be tricked here. Um, this doesn't count as multiple edges in the sense of there's not multiple edges going in the same direction. So, um and there's no loops. It's the last thing that we're checking for each of these. So in that sense, this is going to be a simple directed graph again. Even though there's multiple edges between the Vergis sees, they are not in the same direction. So not counting as kind of representing the same thing. Our very last one here is very similar to D, but now we want toe say that there's an edge for each flight. So back Thio needing six between Boston and Newark child using. But the key here now is that the direction does matter. So we need Thio show show which direction each of these air going in. So let us do this for now. I think that's still clear which way that's going. So for pointing this direction to pointing from network from Newark to Boston between New York and Miami, we'll have five total and three air going from New York to Miami. Two are going from Miami to New York. Go back just a second ever believe in, Um and this is the way we're going Thio her scene So New York to Detroit has one Detroit to New York. Cast him New York Washington's 30. So the New York to Washington is three office attractions to and finally from Washington to Miami. Just have one. So as I'm drawing these arrows again, they're pointing in the direction that they're going, so hopefully that's pretty clear. And so, as we're looking to classify this last one, we do have a directed graph. We have multiple edges between the Verte sees in the sense that even multiple and going in the same direction, Um, and that's really the key here. There's no loops, obviously, but that's the defining characteristic is the multiple edges. So this one is going to be called a directed multi gra. You can see where the name came from, directed and multiple edges, and we're all set

Hello. So uh this is the solution to uh the question. So this is for the uh a park with N. G. D. B. In 441 respectively respectively sorry. And then for the B. We also have that uh the does the N. G. D. Four B. 652 in the C. Part? We got uh they're supposed to be It's supposed to be a. three. So you got a straight three. Okay. So that is not uh for the scholarship question, hopefully you understand it. Thank you very much.

This question is asking us to calculate the mean and standard deviation for each of these students and to relate this to precision and accuracy. So our formula for me is each of our sample values divided by the number of samples we conducted. Standard deviation. The formula for this is the square root of this, sum of each of our values minus the mean, that value squared for each of these, and then you divide it by the number of samples minus one. This question, it's also important to note that the density of water is one g per mil leader, So if you draw saying 150 0.150 mL of water, this is equivalent to drawing 0.150 g of water. So moving on to the calculations for each student, the participant A had values of 0.161 0.147 and 0.142 participant B. Had values of 0.158 0.156 and 0.157 participant C. Had values of 0.143 0.153 and 0.150 We can add each of these up to get the total and divide it by three because we have three samples for each participant to get our mean value. So here we have 0.161 plus 0.147 plus your 0.142 which equals 0.450 We can divide 0.450 by our three samples. And you get a mean of 0.150 g per participant B. We do the same. We add up our values get our total value which here equals 0.471 and 0.471 divided by our sample amount. And we get a mean of 0.157 g here for C. Again, same process, we get a total of 0.446 and divided by three. You get a mean of 0.149 About this is rounded from there we can calculate our standard deviations so far participant A. We have the square root of our first value is your 0.161 minus the mean of 0.150 squared. You add it to r 0.147 minus 0.150 squared and 0.14 to minus 0.15 also squared. And we divide this by end minus one. So we divided by two. When you calculate this out, you get a standard deviation value of zero 0.98 On average we do the same for participant B. Here we have 0.158 and I'll just abbreviate this 0.156 0.157 And we subtract 0.157 which was the mean from each of these values divided by two. And our standard deviation value for participant B is 0.1 We do the same for participants. See I'll abbreviated again for three to a 0.153 and 0.150 subtract the mean of 0.149 divided by two. Remember each of these values needs to be squared after subtracting the mean and you should get a standard deviation of 0.54 Standard deviation is just a basic calculation of the amount the participant is off from the mean, from each of their values. So, using this information. All right, this is an abbreviated format. We have our mean and standard deviation for each of our participants, participant A If you remember the mean was 0.150 Under standard deviation of 0.0 98 participant B 0.14 sorry 0.157 and zero and zero point 001 Lastly for participants, see army, see army was zero point 149 after rounding and 0.54 Now, in order to calculate our accuracy, what they're telling us to do is our mean value divided by our volume that we were supposed to draw and we multiply this by 100%. So here for participant A we have 0.150 divided by 0.150 times 100% equals 100% participant B. We have 0.157 divided by 0.150 And they have an accuracy value of 104.7. No the max accuracy that you want is 100%. Even if you are over 100% that is not better for participants. See we have 0.149 Fight it by 0.150 and we get an accuracy value of 99.3%. Finally they want us to evaluate the precision of each of our participants. And precision is how close their values are each time. So oftentimes when relating precision and accuracy, accuracy is how close you get to the center of the target, whereas precision is how close you get each attempt. So this would be high precision here and this would be high accuracy here. So for student A. Our accuracy was 100% in our standard deviation was 0.98 For participant be accuracy of one oh 4.7 precision of 0.1 participant C accuracy of 99.3% and precision of 0.54 If we consider we want our accuracy to be between 99 and 101% we can eliminate participant be for accuracy, so since we can eliminate participant B, we can pick our best participant based on their standard deviation and precision students see has the better standard deviation. Each of their values varies less with each attempt to draw water into the pipe. It so our best choice for hiring based on precision and accuracy students see.
