Question

A researcher is testing the effectiveness of a new protein supplement that claims to improve physical fitness. To test this claim, a researcher selects a sample of n = 10 college students. Each student is given the new protein supplement daily for six weeks, and then all the participants are given a standardized physical fitness test. For the general population of college students, the distribution of test scores is normal with a mean of µ = 35 and a standard deviation of σ = 2. Assuming α = .05 and the distribution is normal, conduct a hypothesis test. State hypotheses, critical region, observed test statistic, decision, and effect size if significant. Students: 12345678910 Physical scores: 40, 45, 38, 44, 39, 41, 46, 43, 45, 42
