Chapter 11, Problem 47CP

Female for president? When recent General Social Surveys have asked, “If your party nominated a woman for president, would you vote for her if she were qualified for the job?” about 94% of females and 94% of males answered yes, the rest answered no. (Source: Data from CSM, UC Berkeley.)

  1. a. For males and for females, report the conditional distributions on this response variable in a 2 × 2 table, using outcome categories (yes, no).
  2. b. If results for the entire population are similar to these, does it seem possible that gender and opinion about having a woman president are independent? Explain.

Expert Solution
Check Mark
To determine

Explain whether gender and opinion about having a woman president are independent.

Explanation of Solution

Two variables are said to be independent, if the population conditional distributions of variables are same.

From the given information it is observed that about 94% of males and 94% females answered yes for the given question.

Since, it is same for both male and female, it seems possible that gender and opinion about having a woman president are independent.
