Question

Suppose a researcher tests to see if women engage in more aerobic exercise on average than men, and rejects the null hypothesis. What does this mean?

a.) Women and men exercise the same amount on average.
b.) There is a strong positive relationship between gender and exercise.
c.) Women have significantly higher mean rate of aerobic exercise than men
d.) Men have a significantly higher mean rate of aerobic exercise than women.

Answer 1

Solution:-  c.) Women have significantly higher mean rate of aerobic exercise than men.

State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.

Null hypothesis: Women and men exercise the same amount on average.

Alternative hypothesis: Average of Women exercise is more than the men's average.

We have rejected the null hypothesis, that means Women have significantly higher mean rate of aerobic exercise than men.
