1. Participants were weighed underwater and then skinfold measures were taken to determine the regression equation for calculating percent body fat. The Pearson product-moment correlation coefficient between actual body fat (as determined from underwater weight) and the skinfold estimate of percent body fat represents the concurrent validity of the underwater weighing method.

a. true

b. false

2. An athletic training group is interested in whether or not athletes meeting the cutoff score for body fat (BF) percentage also meet the cutoff score of the number ofpush-ups as defined by the American College of Sports Medicine guidelines for exercise prescription.What is the null hypothesis in the scenario?

a. There is no association in the BF and push-up ratio scores

b. There is no association in the BF and push-up categorical scores (meet or not meeting)

c. There is an association in the BF and push-up ratioscores

d. There is an association in the BF and push-up categorical scores (meet or not meeting)
