In a past General Social Survey, a random sample of men and women answered the question "Are you a member of any sports clubs? Based on the sample data, 95% confidence intervals for the
population proportion who would answer yes" are (0.13 to 0.19) for women and (0.247 to 0.33) for
men. Based on these results, you can reasonably conclude that
a. There is a difference between the proportions of American men and American women who
belong to sports clubs.
b. At least 25% of American men and American women belong to sports clubs.
c. At least 16% of American women belong to sports clubs.
d. There is no conclusive evidence of a gender difference in the proportion belonging to sports
clubs.
