convert her score to a z score among the distribution of exercise capacity
above.
12. Alisha’s grandmother has an exercise capacity of 21 minutes, as

the distribution of exercise capacity in Americans over seventy years old.
Who has a relatively longer exercise capacity compared to her peers—
Alisha or her grandmother?
