In the Sullivan Statistics Survey, respondents were asked, “Would you be willing to pay higher taxes if the tax revenue went directly toward deficit reduction?” Treat the respondents as a simple random sample of adult Americans.

(a) What proportion of the males who took the survey is willing to pay higher taxes to reduce the deficit? What proportion of the females who took the survey is willing to pay higher taxes to reduce the deficit?

(b) Is there significant evidence to suggest the proportions of males and females who are willing to pay higher taxes to reduce the deficit differs at the α = 0.05 level of significance?
