There is a stereotype that men are willing to talk about something, even if they admit that they don’t know anything about that something. Using the PewSocial-Media dataset, first select cases so that you’re looking at only those people who said they are “not at all knowledgeable about the U.S.

surveillance program.” Then, run a t-test to contrast men and women on the

“Willingness to Converse about Surveillance Program” index. Explain your results. After you’re done with this exercise, be sure to go back into the Select Cases box and get all of your cases back.
