You are curious about whether senior citizens are more likely to talk with their family than are than college students. In a sample of 30 college students, 20 had talked with their family in the past week. In an independent sample of 35 senior citizens, 27 had done so.
Reading the question, you probably had a hypothesis about which group is more likely to talk with their family. If you believed that senior citizens were more likely to talk to their family than college students were, what would you have done differently in problem 1a to test this intuition explicitly?
