Construct the dotplot. Listed below are pulse rates (beats per minute) of females selected from Data Set 1 "Body Data" in Appendix B. All of those pulse rates are even numbers. Is there a pulse rate that appears to be an outlier? What is its value? $$80\quad94\quad58\quad66\quad56\quad82\quad78\quad86\quad88\quad56\quad36\quad66\quad84\quad76\quad78\quad64\quad66\quad78\quad60\quad64$$

We're doing The men Whitney uses the men with new test is a non parametric alternative toe to test for the difference between two independent mint. This test is often used and situations in which the two samples are drawn from the same population off subject, but different treatments are used. I used on each set in exercise 29. We are required, so verify the summer Friends for Means and the TV. The given table is the data. Each represent the males and females group Group one is males in go to his females. So we need to ring the gods, huh? From the lowest to the highest. So it's one bring through three and for the same. So we had the ranks and divide by three, which is the three, three and three Bring five and six are the same. So we add, and to get back to it should be 5.5, 5.5, seven, eight, 9, 10 and 11 at the same. So we had the wrong sent to a tree. Tributes in same and say self and getting on the same. So we serve 25 7.5, 14, 15 and 16 at the same, so it will be sorry. 14, 15 and 16 are the same, so it should be 50. So this is 15, 16 and 17. So the 16, 16 and 16 18 and 19 the same. 18.5 aging important flag 19. So it's 20 21 23 23 are the same. So it's 22.5, 22.5, 24 25 26 are the same. 25.5, 25.5, 27. 20 age in 29 and one is a quote to 16. And then Sue is a question did in. We need to find the some offerings around. One is the quality some offering for means it's one plus strain. Last Train LA's 5.5 plus seven plus age Last Hand. Last 10 Last 12 25 Last 12.5 Laws. 16 less, 18.5 Last 18 25 Glass. It's windy last time to one last 25.5, and this is a quality 192. Then rank, too, is the quality three plus 5.5 Last 10 That's 14. Lance 16 plus 16 Lance 20 to 25. Last 22.5 plus 24 last 25.5. Last train. The servant last 28. That's 29 and this is equal to so for three, and you can see that. Okay, rings Frank Raines for males, some of friends for males is 1 92 as required. So now we need toe find p value. Finding the Pew video we need. That's value, said Sta, is a cultural you star minus new, which is the mean divided by sigma. So we need to find USTA. You star is a minimum between you won and YouTube. Yeah, you one is a quote room in one my bread buy into last and to spread by into plus one. Do you have a fight? School? May Nas R two, which is equal to 16 not by dating plus 16. So get in described by 18 plus one. Developed by tool minus 2 to 43 This is a culture 56. YouTube is a cultural sorry is it called to anyone? That's right by into plus and one was played by anyone, plus one developed by tool my nose, let alone this is a quality room. 16. That's right by 18 plus 16 that's backed by 16 plus one. Divided by two man has won name, too. She's a Clarkson. One way to since used on is the minimum between U one and U two. You study the quote, too. 56. So now we need to completely mean you Mu is a culture and one much played by end, too. Do it By true, she is equality 16 months, but by 18 divided by two is a quote to wonderful form when I was in full, then Sigma is the squirrels off n one must abide by and to and spread by n one plus and two plus one divided by its where this is a culture. The squirrels off 16. That's right. By six, they're in much bad by 16 blast taking plus one. Divided by 12, she is a call to 22. When 80 So that's the is it quiet, too. 56 minus one 104 divided by thank you too. 0.80 which is a quote to negative 2.11 We don't need to use this start when p that the video p off that stuff less than a quality negative 2.11 is equality we used deviltry for? Is that video in the left hand change from the From table three, The cumulative probability is 0.0 creamy for eight, which is approximately zero point zero 37 three, so we can see that they calculated value for P is approximately the pavilion we were required to verify, which is zero point 0373

Yeah. So for this problem, we're looking at heart rate in beats per minute. For when men and women so simple of yeah, males and females in a certain group. And we wanna find some central measures. So we're going to start with the Mead for males. So 86 plus 72 plus 64 plus 72 plus 72 plus 54 plus 66 plus 56 plus 80 plus 72 plus 64 plus 64 plus 96 plus 58 plus 66. We read that, Fitch. Here we go. More night and you divide all that. Some by the number of entries. So how many entries we have? 123 456789 10 11 12 13 14 15. 123456789 10 11 12 13 14 15. So we have 15 entries. Divide by 15. And that means that the mean for male, that means the pressure is ah, 69.5. So 69.5 beats per minute. Now we want to look for the median. So in order to look for the median, we're gonna need to sort our data and increasing or decreasing order. And then we can support that data in two groups. Eso What's the lowest blood pressure? Is it 54 year citing its 54. So that's right. 54 here and then 56. I think it should be 56. Yes. So 56 what comes after? 56 58 and then we go into sixties. So 64 is something. The winter in 64 no, and 64 appears multiple times. So it appears one, 23 times of 64 64 64 and then 66. It seems there are only odd, not even numbers. So no. 65 66 appears twice so 66 66. Now you've noted that we've entered 1234567 eight observations. And that's enough because we have, in total 15 observations that it's an even number that takes that mean we take the number right in the middle for the median. So we know that we have a group of seven entries and here we're gonna have it. So seven entries right here. We're gonna have seven entries right there. so half of the males in that group had heartbeat lower than 66 beats per minute, lesser or equal to 60 seats beats per minute. And we know that the other half will have a heartbeat greater or equal to 66 beats per minute. But we don't need to know three information in that group. So the media in that case will be 66. We can compute the mean for heartbeat for female. So again, same thing. You simply add everything. So 64% 84 plus everything in the middle until we reach 82 80. Once again you have at 15 and trees, which will give you mean heartbeat of 82.1. So you're left with 82.1. I'm going to scroll down just a little bit so we can have a bit of space to compute the median eso media. And once again, we need to sort our data in increasing order. So what's the lowest? The lowest heartbeat. Heart rate for female. I think it would be 64 which appears once, and nothing is lower then. Is there anything else in the sixties? No, no Seventies we have 70. Which Onley appears once then 74 which also appears on Lee once, I think. Yes, and I forgot. Of course I forgot one entry. We have 68 which was lower than 70. 74. Eso 68 way Have nothing left with in the seventies. Let's move to the eighties. So 80 appears once here 80 82 which also appears which this appears twice. So 82 82 one to So now we have 1234567 So the next entries will be the media and it's 84. So 84. And then again we have 1234567 eight. Our first eight entries. That means this these are the seven lowest values. The next seven values would be the seventh highest values and the value right in the middle of those two groups of seven is 84 which is the median. Uh, Therefore, we can say that half of the female and that sample have a heartbeat lower than 84 beats lower or equal to 84 beats per minute and a half off the female. That sample have a heartbeat greater or equal to 84 beat per minute. Now if we go toe interpretation off what we found since the Buddha mean and the median for heartbeat are greater for female than male. We can say that the males have a lower all right heart rate than women, at least in that man. But Mayor has had a lower heartbeat per minute, then females. So for that simple at the variant. So there you have it, your measures of center and what they represent.

In this question, it was given that 0.8 export with equal to 74.0 and Standard Division with equal to 12.5. The pulse rate is 36 para minutes. To determine the difference between this pulse rate and the mean off 74 we get X minus export equal 36 minus 74 for equal to negative 38.0, moving to the next point B Given export equal 24 and stellar division also equal to well 0.5, the pulse rate will equal toe 36 31 minutes. To determine the difference. We get the difference all also equal to X minus X ball Negative 38.0, we divide these difference by the standard division yet X minus export over standard division with equal to negative 38 over 12.5 or equal to ST negative 3.44 Then this means that this difference, then this means that the difference is three point off forced on the divisions, moving to the next point which is C for the same givens. After we did your mind, the difference for equal to Nick to 38 going to all, and we divided by the standard divisions. We get negative 3.44 and we consider that there's the pulse rate off 36 ft per minute. Is three point offer standard divisions below the mean? Because it's negative. We measures that school, which is the number off standard divisions, that the value is from the mean and a positive is that the school indicates that the value above them and negative city school in the case that the value below the mean thus is the score is in this case is nicked a 3.44 which is a very equal to make the 3.44 which is below the mean moving to the next point, which is deep for your scene. Givens, after we get that school for negative three point off, all is that at the school is significant, and the post rate off 36 beats per minute is also significant and doesn't find an answer for this question. Thank you

So men had a pulse rate average of 64 and females had an average of 69.6 beats per minute. What we can conclude from this is that these two numbers are different, and that means that there beats per minute for the males and the females are different. The second part of the question says, with a larger sample size, like, say, maybe a 500, something Lot bigger than just the 10 that we sampled. Would that lead to better results? And that would be a resounding? Yes. Yeah, more samples. Better data.
