Question

A particular personal trainer works primarily with track and field athletes. She believes that her clients run faster after going through her program for six weeks. How might she test that claim? Multiple Choice A hypothesis test for p1 −p2 . A hypothesis test for μ1−μ2⋅ A matched-pairs hypothesis test for μD. We are unable to conduct a hypothesis test because the samples would not be independent.

Answer 1

A matched-pairs hypothesis test for μD

Explanation:

The trainer wants to compare each athlete's time before the program to the time after the program. Since we're comparing times for the same athlete, the data is paired, so we should use a matched-pairs test.
