> Question 11 4 pts Twelve healthy men who did not exercise regularly were recruited to take part in a study of the effects of exercise on oxygen uptake. The response of interest is the change of maximum oxygen uptake after participating a 12-week exercise program. The ages of the 12 subjects are x = (21,22,23,24,25,26,27,28,29,30,31,32), the corresponding changes in maximal oxygen uptake are y = (-0.87.-10.74,-3.27.-1.97,7.50 -7.25, 17.05, 4.96, 10.40, 11.05, 0.26, 2.51). We fit the following linear regression model: Y; = a +B(B1 - 7) +€, where e N (0,0%).
