Determine the whole number of standard deviations that includes all data values.
The mean price of the nonfiction books on a best-sellers list is $\$ 25.07 ;$ the standard deviation is $\$ 2.62 .$ $\$ 26.95, \$ 22.95, \$ 24.00, \$ 24.95, \$ 29.95, \$ 19.95, \$ 24.95, \$ 24.00, \$ 27.95, \$ 25.00$

This question, we are told that the number of pages in a PDF document has a discreet uniform distribution from five 29 pages and were asked for the mean and standard deviations of the mean here is basically nine plus 5/2, which is seven. And the standard as for the standard divisions of standard division is square root of the variance, the square root of B minus a plus one squared minus one over. Well, so 9 -5 days 44 plus one is 55 squared Is 25, 25 -1 is 24 sq root of 24 over 12, which is basically the square root, both to Which is 1.41.

Okay, this problem we first formalised the information that we got the meal is Send 8.01 and the standard deviation of the population is 7.61. This is our These are the information that we get. We also have the simple sizes 40 because it's large enough, we can assume that the distribution of the sample mean is standard, um normally the spirit. So so first we calculate difference, We're going to cover 8144 seven, And it's going to be straight .43. So we want to calculate it mm the property that is in the difference of here. And first we can calculate a standard deviation of the sample mean, Which is 7.61. So yeah let's do some mess here. Uh it's gonna be sigma over squared event and the sigma here is here and and this year. So we got 6.7.61 over square of 40 And the answer is 1.2. Mhm. So uh good answer is three point 4 3/1 40.2 and the answer is 2.8086 finds a hour and the answer is 0.99 17 79 So because in the problem we're going to calculate the probability that there's such a graph is greater than this part than uh huh. Through Than 2.86. So we would like to use the 1- it. Just remember that this is the region that we want to calculate. So the probability It's gonna be a 1 -9979 And then this .0021 which is 2.1%. And the assumption is that uh this one follows the the sample follows the a standard normal distribution. So this is something practice. Mhm. Okay. Okay. It's a number distribution. And this is our answer. Yeah. The probability that is grilled and given

Okay, First off, you're going to make sure you have a graphing calculator that has the normal CDF function available. To be able to finish, figure out this problem. Um, if you don't have a calculator with that function, you can go online and just type into Google Online calculator with normal CDF, and it should be able to find you something that you can use online. But assuming that you have found something some sort of calculator, either in person or online, that can do normal CDF we need four pieces of information. We need a mean a standard deviation. We know Lowe in a Hi. We're told that our mean is going to be eight for this. We're told that our standard deviation is one. This one is interesting because what it's asking us is find the probability for when seven is less than or equal to X. Well, first off, we don't need a ready like that. Why don't we write that inequality the way that it's actually useful to us? Which would be that X is greater than or equal to seven, meaning it's asking us to go on the normal distribution from seven to the right. Well, that means seven is gonna be my lowest number. I had not caring about anything lower than seven. I'm not really sure what my high is. I want to make sure that I am counting everything to the right. So to figure out what my high is really the safest way to do it would be too quickly. Just go ahead and graph at a normal distribution. OK, so the idea would be we have a mean I'll draw flowers. We have a mean of eight one standard deviation would be adding and subtracting one. So eight plus one is 98 minus 17 I'm not interested in anything lower than seven. So I'm not gonna do any standard deviations to the left. But I will keep doing standard deviations above the mean to the right. So second, standard deviation would be nine plus one, which is 10 third standard deviation would be 10 plus one, which is 11. Remember? We know 99.7% of our data is kept within three standard deviations due to what we have learned. Um, earlier here, we want to make sure we cover everything, So I do need to G O. Another standard deviation out. Just to make sure I cover everything, 11 plus one would be 12. There should not be anything else after 12. So if you make 12 year high here for your calculator, you should be able to get yourself the right answer. If you plug in a low of seven high of 12 Univ. Eight and a standard deviation of one, the calculator should give you zero point. Lips didn't change. My color should give you 0.8413 which would then round to be 0.84 That would be your probability for this one.

No result this problem. You are going to need a calculator that has what we call a normal CDF function on it. More than likely, that will need to be a graphing calculator If you have one. There are online calculators available. Simply go to Google or some other search engine and type in online calculator with normal CDF, and it should bring up something online that you can use. Um, once you find that there's gonna be four pieces of information that you need to give that calculator so that it can calculate this probability for you, it's going to need you to give it low. The high, the mean and the standard deviation, mean and standard deviation of brought me the first things you guys were given. Ah, in this case, were given a mean of six and a standard deviation of three. Okay, and then it's asking us to find the probability for when X is between two and seven, right? That's what that compound inequality is saying to is less than or equal to X is less than or equal to seven. That's meaning that's asking for what's the probability? Whenever X is between two and seven. So too would certainly be your low as the lower number. And seven would certainly be your high as the higher number. I don't know why I just read that backwards. I'm sorry too. Seven. There we go. Make sure if you're using you can clear that you are plucking them incorrectly. Okay. Meaning I'm I listed the order than most calculators taken. Obviously, I can't promise every single calculator is exactly the same way, so make sure you check yours. But most calculators should be asking you in the order of low high, mean and standard deviation. If you plug it all in correctly, you should get back from your calculator. A probability of zero point 5393 or somewhere around there, depending on how many digits. Okay, we are asked around to the hundreds place. So that means for us we would round that up to a 0.54 as our probability
