John wants to compare the average time area high school students spend studying per week with the regional average, 20.5 hours. John surveys 25 randomly selected local high school students, asking how much time they spend studying in a typical week. Graphs of his sample data show no strong skewness or outliers. Choose the correct inference procedure that John should use to test if the mean weekly study time from his sample differs from 20.5 hours: one-sample, two-sided z-test for a proportion one-sample, right-tailed t-test for a mean one-sample, left-tailed t-test for a mean one-sample, two-sided t-test for a mean
