6. Estimating p 2 p 1 2 to within .05 with probability

.98. Assume that the sample sizes will be equal, but that you have no prior knowledge about the values of p1 and p2. Suppose you want to estimate one of four parameters—m, m 2m , , 2 1 2 1 2 p or p p —to within a given bound with a certain amount of confidence.

Use the information to find the appropriate sample size(s).
