A random sample of 60 Pennsylvania high school seniors was taken. They provided information on their sex, and whether or not they support affirmative action in college admissions. The sample consisted of 31 females, 26 of who support affirmative action, and 29 males, 17 of who support affirmative action. Is there a difference between the sexes on their support of affirmative action? Also, estimate this difference at a 90% level of confidence.
