Question

6. A researcher just finished watching Tiger King and thinks that the viewers have different opinions on Doc Antle based on their demographic. Specifically, she thinks women will have a more negative view of Doc Antle than men. To test this, she polls a sample of n = 15 women and n = 15 men and asks them to rate him on a scale of 1-10 (1 indicating he is the worst, 10 saying he’s a role model for all Americans). Below are the results she found: Opinions on Doc Antle Women Men n = 15 n = 15 M = 2 M = 3 SS = 14 SS = 14

a. What type of t test would you run to determine whether or not a difference exists between men and women’s opinions on Doc Antle?
