In each​ case, find the approximate sample size required to construct a

95% confidence interval for p that has sampling error

SE=0.07

a.

 Assume that p is near

0.4

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.
