Suppose a university advertises that its average class size is 36 or less. A student organization is concerned that budget cuts have led to increased class sizes and would like to test this claim. A random sample of 40 classes was selected, and the average class size was found to be 38.4 students. Assume that the standard deviation for class size at the college is 7 students. Using a = 0.05, complete parts a and b below. a. Does the student organization have enough evidence to refute the college's claim? Determine the null and alternative hypotheses. Ho:u 36 : s Hq: H, :μ > 36 The z-test statistic is a (Round to two decimal places as needed.)
c) the critical z-score(s) are __
D) because the test statistic ____ ____ the null hypothesis
