(a) Let p represent the proportion of all corporations preferring a nonsmoking candidate. Find a point estimate for p. (b) Find a 0.95 confidence interval for p. (c) As a news writer, how would you report the survey results regarding the proportion of corporations that hire the equally qualified nonsmoker? What is the margin of error based on a 95% confidence interval?
