competitive rowers: a group of skilled rowers and a group of novices. The researchers measured the angular velocity of each subject’s right knee, which describes the rate at which the knee joint opens as the legs push the body back on the sliding seat. The sample size ?, the sample mean, and the sample standard deviation for the two groups are given below.
