A researcher is interested in comparing the resting pulse rate of women who exercise regularly and women who do not exercise regularly. She wants to perform a hypothesis test to determine whether the mean resting pulse rate of women who exercise at least 6 hours per week is less than the mean resting pulse rate of women who exercise less than 6 hours per week. Identify the outcome variable for the proposed hypothesis test.

Hours of exercise per week

Resting pulse rate

Difference between mean resting pulse rate of women who exercise regularly and mean resting pulse rate of women who do not exercise regularly.
