A physiologist wishes to study the effect of birth control pills on exercise capacity. Five female subjects who have never taken the pill have their maximal oxygen uptake measured during a treadmill session. The five subjects then take the pill for a specified length of time and their uptakes are measured again, as given below. Do the data provide sufficient evidence to indicate that the mean maximal oxygen uptake after taking birth control pills is less than the mean uptake before taking the pill? State the null and alternate hypothesis.

MAXIMAL OXYGEN UPTAKE
SUBJECT BEFORE AFTER

1 35.0 29.5

2 36.5 33.5

3 36.0 32

4 39.0 36.5

5 37.5 35.0
