b. What is the standard error of the point estimate in part (a)? c. How would you compute an estimate of the standard error found in part (b)? d. Suppose that n₁ = 200, X₁ = 150, n₂ = 250, and X₂ = 185. Use the results of part (a) to compute an estimate of p₁ - P2. e. Use the results in parts (b) through (d) to compute an esti- mate of the standard error of the estimate. 7.3.11 Of n₁ randomly selected engineering students at Ari- zona State University, X₁ owned an Apple computer, and of n2 randomly selected engineering students at Virginia Tech, X2 owned an Apple computer. Let p₁ and p2 be the probability that randomly selected ASU and Virginia Tech engineering students, respectively, own Apple computers. - - a. Show that an unbiased estimate for p₁ = p2 is (X₁/n₁) — (X2/n2).
