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 12week exercise program. The ages of the 12 subjects are x = (21,22,232425,2627,2829303132}. 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}.
