Suppose you want to compare the amount of student loan debt for males and females at StatCrunch U. The null hypothesis for this problem would be that there is no difference in the mean amounts of student loan debt for males and females and the alternate hypotheses would be that there is a difference in mean amounts of student loan debt. Using the sample you downloaded in StatCrunch, conduct a randomization test for two means with 3000 randomizations. (Your input menu should be as follows.)
Post responses to the following:
explain why the typical hypothesis that analysts want to test is whether a particular regression coefficient (B) is equal to zero (H0: B = 0) versus whether that coefficient is not equal to zero (H1: B ≠ 0).
