Frustrated passengers, congested streets, time schedules, and air and noise pollution are just some of the physical and social pressures that lead many urban bus drivers to retire prematurely with disabilities such as coronary heart disease and stomach disorders. An intervention program designed by the Stockholm Transit District was implemented to improve the work conditions of the city's bus drivers. Improvements were evaluated by G. Evans et al., who collected physiological and psychological data for bus drivers who drove on the improved routes (intervention) and for drivers who were assigned the normal routes (control). Their findings were published in the article "Hassles on the Job: A Study of a Job Intervention With Urban Bus Drivers" (Journal of Organizational Behavior, Vol. 20, pp. 199-208). Following are data, based on the results of the study, for the heart rates, in beats per minute, of the intervention and control drivers. a. Obtain dotplots for each of the two data sets, using the same scales. b. Use your result from part (a) to compare the two data sets.

Okay so this is the normal probability plot. Uh nice straight line we got here uh sample size of 41. So definitely a moderate to large sample size. We're doing this at the 10% significance level. So we're good to go with this test. Okay The first quartile is between 74 and 75. So we get 74.5. Third quartile is at 90. We have a minimum value of 58. Maximum value of 100. The i. r. is 90 -74.5. And there are also no outliers. So that's what our box plot is going to look like now for the history graham we got bins set up to look like this. Um the first been for me is between 50 and 60, there's just a difference of 10 in between each one. So that's what it looks like. We got a frequency of 14 12, 12 and 12 actually went on it right there and 4 12 12 and 12. The stem and leaf plot is gonna look have this general shape like this. And for our mean we get 81.756 as we sum up and divide by the sample size now for the variance. Uh We get this And it is 105.589. Now for the hypothesis test U. is equal to 80. And the alternative is that new is greater than 80. So for a. T statistic it's going to be 81.5 cents 56 minus 80 divided by the square root of this number. Right up here, Divided by the square to 41. We get approximately 1089. And if we're looking back to the book for students distribution with 40° of freedom, we get a p value that is greater than 10%. Therefore we fail to reject the null hypothesis at the 10% significance level.

I don't have all the information for this problem, but I do know is that N is equal to 41 samples? Has is 41. The alpha level is 10%. Are null hypothesis is that the average is 80 mg. And the alternative hypothesis, we're trying to find out if it's higher, so the average is gonna be 80. Ah This means that we are doing a right tailed test for the next part. We can do you can do start doing the ranks. When we do the ranks, We got to make sure that we don't have zero. If we have a zero, that means that we reduce the we do reduce end by one times, however many times it happens. So X. So then once you throw out to any zeros that you have, if any, you'll get a W value just by adding up all the positive ranks. That just means that whichever ones you found that were positive, um that were greater than the mean. He didn't throw those out and he found out which one was largest or you went from assigned won a rank of one of the smallest number. If there was a tie, you would add up what those ranks would be. For example, for four and 5. That would mean that they would both get a rank of 4.5. Uh So once you get that bank of W, you'll find that Z score, but before you do that, you still have to figure out, oh actually we're not doing the W test, the completion. We just need to find out what the W score is and then you can plug it into the sea test. Um It was the long part from them later on the book. It's not even later on in the same chapter, but this is the formula, copied it down. You're gonna plug in that W score right there and then you're going to get some approximate value. Probably use two decimal places. Maybe even more if you have two or three. And then to find out what that is you're gonna find out your P. Value, it's going to be equal to P. Z. Since you're doing the right tail test. It's gonna be easy. Uh It's greater is greater than whatever you receive value found there it's gonna be easy not is greater than C. Mhm. Uh And then you're gonna get that P. Value And if it is you're going to compare it to 10%. If it's larger than 10% then you are going to fail to reject. However if it is less than Then you're gonna rejecting all hypothesis and in any case it's gonna be at the 10% significance level. Yeah.

So in this problem, we have been given that number of charter bus company charges affair of $40 per person plus $2 per person for each and source it on the bus. If bus holds 100 passengers and X represents the number of each, a number of unsold seats, How many passengers must ride the bus to produce revenue of fine. $+950 because of the community? To also know the fact that because of the company's commitment to efficient fuel use, the charter will not run unless filled to at least half capacity. All right. So now, uh let's suppose that there are X unsold seats. So therefore revenue, but a passenger would be Equal to 40 plus two weeks from the given condition in the question. No. This has given us to be equal to fine. Yeah. So now a total revenue would be equal. Do it would be equal to 100 -6. Discriminate. Since there are excellent sold seats, the number of passengers will be equal to 100 -6 and do 40-plus 2 weeks which is revenue by each passenger. Yeah. So therefore this would be the total revenue which has given us to be equal to fine nine $50. So once we have equipped these two we will be getting a quadratic equation which would be to work square -160 x Plus 1950 equal to zero. Now, once we solve this we will be getting to values of X which will be X is equal to 65 or 15. Now if X is equal to 65, the number of passengers will be For X is equal to 65. Number of passengers is equal to 100 -6 which is equal to 35 Which is less than half of the capacity which is 50. So therefore because of the company's commitment, if you efficient, you use the charter with not well. So therefore The value of X will be equal to 15, and hence the total number of passengers would be equal to. The total number of passengers would be quarto 100 -6, which is 85. So this is the answer. Thank you friends. I hope you like the video.

Here in this question. When X peering bus stop, suddenly passengers are thrown forward from their seats. Because Then there are four options given first option please. The back of seat suddenly pushes them passengers forward. Then the second option in inner self rust stop bus and take the body forward. And the third option is upper part of the body contained to be in the state of motion. Whereas the lower part of the body in Kandahar to the seat remains at the risk. Then the last option is upper part of the body come tourist, whereas the lower part of the body is called out to the seat begins to move here when a bus they're just moving fastly currently come to rest them down. Upper part of the body continue the state of motion. And there is a person here in the bus. It when it comes suddenly to stop, then the upper part of the body continues in the motion whereas the lower what of the body which each other golden though with the body. How come interesting. So options sees our answer that is upper body turned a upper body a poor body condition, the state of motion or continues in the state of motion. But it's not in our body abroad contains in the state of rusted for the state of moshe, we're a slower lower bully having having conductivity see to remain a trust. So in this question option sees our answer. Well because when they're spiritually moving bus suddenly stop then Yeah, proportion, continuing the emotionality. The personality in the seat or interest still remains at first. so this is our answer.
