6) At a fitness boot camp, the leaders have devised two different obstacle courses. Several boot campers have familiarized themselves with the courses. A random sample of 7 campers are chosen at random and run both courses. The times to run the courses are noted below. (7 pts) Test: 1 2 3 4 5 p-value .02 .001 .13 .003 .23 Camper Hard course (secs) Easier course (sec) 1 126.3 90.5 2 119.0 82.7 3 152.1 116.0 4 136.5 101.0 5 155.7 119.1 6 164.8 129.6 7 171.4 134.6 Construct a 95% confidence interval for the mean increase in times to run the hard course.

Step 1
To do this, subtract the time taken for the easier course from the time taken for the hard course for each camper. Camper 1: 126.3 - 90.5 = 35.8 Camper 2: 119.0 - 82.7 = 36.3 Camper 3: 152.1 - 116.0 = 36.1 Camper 4: 136.5 - 101.0 = 35.5 Camper 5: 155.7 - 119.1 = Show more…

A coach uses a new technique in training middle distance runners. The times for 9 different athletes to run 800 meters before and after this training are shown below. Athlete: A, B, C, D, E, F, G, H, I Time before training (seconds): 115.2, 120.9, 108.0, 112.4, 107.5, 119.1, 121.3, 110.8, 122.3 Time after training (seconds): 116.0, 119.1, 105.1, 111.9, 109.1, 115.2, 118.5, 110.7, 120.9 Construct a 99% confidence interval for the mean difference of the "before" minus "after" times. Use the traditional method of hypothesis testing to test the given claim about the means of two populations. Assume that two dependent samples have been randomly selected from normally distributed populations.

Test the effect of a physical fitness course on one's physical ability; the number of sit-ups that a person could do in one minute; both before and after the course; was recorded. Ten individuals are randomly selected to participate in the course. The results are displayed in the following table: Using this data, find the 95% confidence interval for the true difference in the number of sit-ups each person can do before and after the course. Assume that the numbers of sit-ups are normally distributed for the population both before and after completing the course. Show supporting work for each step that follows: Lower endpoint Upper endpoint

A random sample of high school track athletes ran an 800 m time trial before their first practice of the season, and another one after practicing for three weeks. The results are given below (times given in seconds). Assume an approximately normal distribution, if necessary. Use the sample data to construct a 99% confidence interval for the mean difference between the before and after readings.
