Question

You collect data on N = 25 student weights and find that the average student weight in your sample is 135 pounds. The sample standard deviation (s) is 5 pounds. You conduct a two-sided hypothesis test where H0: μ = 134 pounds. Which of the following statements are true: I. You reject the null hypothesis when α = 0.05 II. You reject the null hypothesis when α = 0.01 III. The test statistic (T) equals T = +1
