Suppose that 247 of the 544 people in the control group survive an additional 6.9 years. Suppose that 471 of the 681 people in the surgery group survive an additional 6.9 years. Let p 1 be the population proportion of the control group who would survive an additional 6.9 years. Let p2 be the population proportion of the surgery group who would survive an additional 6.9 years. A 99% confidence interval on ( P1 - P2 ) can be shown to be ( - 0.309, - 0.1662 ). (a) Determine the most reasonable estimate of ( P 1 - P2 )- A. 0.0714 OB. -0.5861 OC. 0.2376 OD. 0.5861 OE. -0.0008 OF. -224 OG. -0.1428 OH. -0.0714 OL.-0.2376 OJ. -0.0277 OK. 224 OL. 0.1428 OM. 0.0277 ON. 0.0008 50.0 (b) Determine the standard error of your estimator from part (a).
