Formaldehyde Exposure. One use of the chemical formaldehyde is to preserve animal specimens. In the article "Exposure to Formaldehyde Among Animal Health Students" (American Industrial Hygiene Association Journal, VoL. 63, pp. $647-650$ ), A. Dufresne et al. examined student exposure to formaldehyde. In the course of their lab work, 18 students at cach of two animal health training centers were exposed to formaldehyde. Testing equipment recorded the total amount of formaldchydc, in milligrams per milliliter (mg/mL), to which cach student was exposed. The results are presented on the WeissStats CD. a. Obtain boxplots and normal probability plots of the two samples. b. Based on your results from part (a). given the choice between using a pooled $t$ -test or a Mann-Whitney test, which would you choose? Explain your answer. c. Use the test that you chose in part (b) to decide whether the data provide sufficient evidence to conclude that there is a difference in median formaldehyde exposure in the two labs. Perform the required hypothesis test at the $5 \%$ significance level.

For this problem. We have methanol, which is used for various types of cooking, very flammable reacting with oxygen, producing carbon dioxide and water. And it mentions that 363 Killah jewels of heat are produced per mole of methanol. So let's right the balanced chemical reaction. We have methanol, which is ch 30 h reacting with oxygen producing carbon dioxide and water. We have three and one. We have formals of hydrogen on the left hand side, and we have two moles of hydrogen on the right hand side so we can put it to right there. Then we look at the one mole of carbon and one bowl of carbon within. Look at the number of Oxygen's and we have 1 to 2 here. 34 On this side, we have one, 23 So with this one, we actually need three. Oxygen's out of two. So this is an example of where, before I said, we're gonna end up with an odd number of oxygen's on one side, so we need to increase the number of carbons or hydrogen is we have so that we could get an even number of oxygen's. Here's an example, where we end up with an odd number of oxygen's on the left hand side, and we're gonna end up having to use a fraction in order to balance the oxygen's three halves. Times two is 33 plus one is four. That gives us the four oxygen's we have on the right hand side. So way to avoid that now is the multiply everything by two. So we get to method alls. We get three oxygen's, we get to carbon dioxides and we get four hydrogen ins. Then we need to add the heat. The heat is 3 63 killed Jules per mole of methanol. We now have two moles of methanol reacting, so it's gonna be two times 3 63 or 726. Killer jewels of energy will be released when the two moles of methanol react in this balance chemical reaction and for Part B and asked if it's an endo thermic or an extra thermic reaction if the heat is being released, heat is a product. It's definitely an extra thermic reaction. How many moles of oxygen will react with the particular number of moles of methanol? That amount is 0.450 Moles, methanol All we need to do is look at the Sochi metric relationship between the methanol and the oxygen, which is 2 to 3 that we determined from our balanced chemical reaction so we can convert the moles of methanol in two moles of oxygen. With this ratio, which is 0.675 moles 02 they're required to react with 0.45 Moles of methanol. The last part of this problem asks for a mass of carbon dioxide required to react with 78 grams of methanol. We'll start with our 78 grams of methanol. We'll cover the 78 grams of methanol two moles methanol by determining the molar mass of methanol, which is determined by taking one times the muller massive carbon plus four times the molar mass of hydrogen, this one time similar massive oxygen. Can we get 32.4 grams of methanol per mole of methanol? Then we were in units of moles. Methanol. You can convert moles methanol into moles of carbon dioxide. Seeing that there's a to to to relationship. So essentially the moles of methanol that react will be equal to the moles of carbon dioxide created. Then we were in units of carbon dioxide. We can convert to grant carbon dioxide knowing the molar mass of carbon dioxide, which is 44.1 which was determined by taking one time similar massive carbon plus two times more massive oxygen would get 100 and seven grams of carbon dioxide that will be produced from 78 grams of methanol.

All right, so in this question, they tell us that they've centrifuge a cell solution. And when you centrifuge something you spinning around really fast in a circle and the heavy stuff gets collected at the bottom and we call that a pellets. So they want to know what is making up this pellet be? So the one hit that they give us is that whatever is making a pellet be consumes a lot of oxygen. So really, what the question is asking is not so much what has to do a centrifuge ing, they just want to know. Do you know what the different organelles do and which one has something to do with oxygen consumption? So if we think about our options, the 1st 1 is a rival zone, and Riva zones make proteins, so making a protein does not have a whole lot to do with oxygen consumption. But our second option is a mitochondria, and I'm on a con tria. They kind of look like those little jelly beans. And they've got that inner membrane. Well, his exact guy and they produce a T p, which is so energy to make a teepee, they consume glucose which is sugar, and they also consume oxygen. So Monarch Andrea consume a lot of oxygen to make a teepee. So right off of that magic Andrea is our best answer. But we want to go ahead and check the other three just to make sure our 3rd 1 is evac you a ll factual ls have to do a storage. Not really oxygen. The Golgi apparatus has to do with packaging, not consuming oxygen. And the nuclei is going to store genetic information, which yet again has nothing to do with consuming oxygen. So our best bet is going to be the model Kandra. Because the mitochondria it takes in glucose, it also takes in oxygen. So it consumes both of them and it produces a teepee. So Mata Kandra will be consuming oxygen. So your best answer is mitochondria. That means that that mitochondria is what is in your pellet that they have shown you

Yeah. So if the p M. R is given by this constant a times mass raised to the 3/4, what are the units of this constant? A well, BMR is units of power. So units of power is in um energy per second. In si units, usually jewels per seconds, which is watts. So I only have to do is take the unit for mass, which is kilograms. Move that over here and we get the units for a usually given like this units for a is jules per second times kilograms To the 3/4. So if we have a person that has an A. Of 3.4 and their way 75 kg, What's the BMR? Well, we just use the equation right there, right, With the 3.4 75-3/4. Because these are also units, kg for masses, etc. Watts for power is etc. We put those together and we get About 86.65 watts. Or you can just do a w for what's you don't need to write it up. So what is the A value? If the BMR, It's 460 watts. And the mass is 700 kg for this bear. We do 460 Divided by 700 race to the 3/4 And we get an a of about 3.38 and last little bit here. Yeah, Is a two parter. If we have 180 kg Gorilla With a BMW of 170 watts. What is the BMW of a £1,000 gorilla. Well, the first thing is we got to find out what the A value is, Right? So let's do 170 watts, Divided by 180 kg raised to the 3/4. It will get an A. Of about 3.46. Now the next step is very easy. We have the masses 1000 kg. We have are a value and we need our BMR. So our BMR is this 3.46? We just solve for times 1000 raise to the three quarters, and we should get a B. M. Are about 615.3 watts.
