Question: A study of the effects of physical training on post coronary patients included measurements on maximum oxygen uptake, which was determined for each of 13 patients before training began. After 6 months of bicycle exercise 3 times per week, each person’s oxygen uptake was determined again. The oxygen uptake observations are stored in the data file OXYGEN_UPTAKE.

MTW

. At the 5% level of significance, use MINITAB to test whether exercise tends to increase the maximum oxygen uptake in post coronary patients.
