Question: In each case, find the approximate sample size required to construct a 95% confidence interval for p that has sampling error SE = .06. a.

In each case, find the approximate sample size required to construct a 95% confidence interval for p that has sampling error SE = .06.

a. Assume that p is near .3.

b. Assume that you have no prior knowledge about p, but you wish to be certain that your sample is large enough to achieve the specified accuracy for the estimate.
