Assuming that n, =n,, find the sample sizes needed to estimate (p, -p,) for each of the following situations. a. SE= 0.14 with 99% confidence. Assume that p, s 0.7 and p, 0.6. b. A 90% confidence interval of width 0.76. Assume that there is no prior information available to obtain approximate values of p, and p,- c. SE =0.14 with 90% confidence. Assume that p, s 0.37 and p, 0.9. P2 a. What is the sample size needed under these conditions? (Round up to the nearest integer.)
