Suppose a university advertises that its average class size is 31 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 42 classes was selected, and the average class size was found to be 32.5 students. Assume that the standard deviation for class size at the college is 8 students. Using α = 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:μ = 31 H₁: > 31 The z-test statistic is. (Round to two decimal places as needed.)

In class, we only discussed computational specifics of one of three types of t-tests. However, we had an overview of the different types and when they might be used. Which of the following is not a situation in which some "flavor" of t-test could be an appropriate statistical choice? O Comparing a sample mean to a population mean when you don't know the population standard deviation O Comparing means between exactly two independent groups Comparing two related groups of means (e.g., pre/post scores from the same individual) Comparing means across three or more groups.
