Question:

A study samples n=25 adults. Each adult is given 100 grams of protein for four weeks and then each adult is given a fitness test. For the population, scores on the fitness test are normally distributed with a u= 70 and = 15. The sample of 25 adults has a mean fitness score of M=75. Are these data sufficient to say that protein has a significant effect on fitness? Use a two-tailed test at the .05 alpha level. Compute Cohen's d for this study and interpret it
