Ii. What is the range for the p-value? (use results of part (n) to assist youl iv. Write your conclusion in a complete sentence b. Construct a 99% confidence interval for the difference in mean bone mineral density after 12 months, u n1 0.05 Sports Illustrated surveyed a random sample of 757 Division 1 college athletes in 36 sports. One question asked was, "Have you ever received preferential treatment from a professor because of your status as an athlete? of the athletes polled, 225 said Yes'. Table C is attached. sample proportion, P, of athletes who have received preferential treatment from a professor? rn ? what is the standard error of Construct a 95% confidence interval for the proportion of athletes who have received preferential treatment from a professor. C.Explanation / Answer
a) p_hat = 225/757 = 0.297226
b) SE = sqrt(p_hat * (1-p_hat)/N) = sqrt(0.297226*0.702774/757) = 0.016611
c) For 0.05 signficance level, zcrit = 1.96
95% CI = p_hat +/- zcrit * SE = 0.297226 +/- 1.96*0.016611 = (0.264668, 0.32978)
