For a second 6- month period, we used physically guided practice with the same individuals. For each 6-month session, we collected ratings on the level of required assistance (high = bad) for each person. The data for each individual follows (on the next page). Was the assistance significantly reduced in the second 6-month period?

13.2.4VO2-max Aerobic Fitness Measurements The data set given in DS 13.2.4 extends the data set used in Problem 12.2.6 to include an individual's heart rate at rest, percentage body fat, and weight, together with the variables age and VO2-max considered before. Fit a multiple linear regression model to assess whether the new input variables heart rate at rest, percentage body fat, and weight, together with age, can be used to provide an improved model for VO2-max. What model would you recommend? (This problem is continued in Problem 13.4.3.)

An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores? Let d = (verbal SAT scores prior to taking the prep course)-(verbal SAT scores after taking the prep course). Use a significance level of α = 0.05 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course.

Over at NAIA, you are observing the average length of flight delays (excluding flights that leave on time). Your notes for ten randomly chosen days are here: Day Ave. delay (hrs:min) 1 2:00 2 1:48 3 0:19 4 0:25 5 2:18 6 0:43 7 0:13 8 0:17 9 0:34 10 3:12 If the airport claims that the delays will be no more than an hour on average, check his claim by doing the following: (a) Write the null hypothesis. (b) Write the alternative hypothesis. (c) Formulate and calculate the test-statistic. Is it a one-tail or two-tailed test? Did the airport told you the truth at 95% confidence level? (d) Determine the confidence interval

An instructor for a SAT preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 10 students the first two times they took the SAT. Before taking the SAT for the second time, the students took a course to try to improve their critical reading SAT scores. At a = 0.01, is there enough evidence to support the instructor's claim? 1 200 300 2 350 420 3 250 300 4 330 390 5 200 240 6 370 480 7 320 350 8 270 300 9 220 290 10 310 350
A researcher is conducting a test to see if handedness (right or left) affects the speed at which people perform a particular task. The researcher only knows the order in which the contestants finished. When the data are summarized (with R for right-handed and L for left-handed) the order of finishing (fastest to slowest) was: R, R, R, R, L, R, L, R, L, L Is there statistically significant evidence of an effect of handedness on the speed? Test statistic: The name of the statistical table, degrees of freedom (if appropriate), and the numerical value of the critical value for this test: P-value: Circle an appropriate conclusion: • There is significant evidence that left-handed contestants will finish the task faster. • We cannot reject the hypothesis that handedness has no effect on the time to finish the task. • There is significant evidence that right-handed contestants will finish the task faster.
