To investigate the effect of four treatments on change in body fat mass each of 74 male subjects who were over age 65 was assigned at random to one of the following four treatments: (1) placebo "growth hormone" and placebo "steroid" (denoted by P + P), (2) placebo "growth hormone" and the steroid testosterone (denoted by P + S), (3) growth hormone and placebo "steroid" (denoted by G + P), and (4) growth hormone and the steroid testosterone (denoted by G + S). The accompanying table lists data on change in body fat mass over the 26-week period following the treatment. Carry out an F test to see whether true mean change in body fat mass differs for the four treatments if N = 74, grand total 7 = -157.5, and = T/ N = -2.128.

Transcribed Image Text:To investigate the effect of four treatments on change in body fat mass each of 74 male subjects who were over age 65
was assigned at random to one of the following four treatments: (1) placebo "growth hormone" and placebo "steroid"
(denoted by P + P), (2) placebo "growth hormone" and the steroid testosterone (denoted by P + S), (3) growth hormone
and placebo "steroid" (denoted by G + P), and (4) growth hormone and the steroid testosterone (denoted by G + S). The
accompanying table lists data on change in body fat mass over the 26-week period following the treatment. Carry out an F
test to see whether true mean change in body fat mass differs for the four treatments if N = 74, grand total 7 = -157.5,
