Assuming that the two sample sizes are the same, find the sample sizes needed to estimate the difference in population proportions correct to within 0.03 with a 90% level of confidence. From prior experience we have an estimate of p1 that it is equal to 0.70 and an estimate of p2 that is equal to 0.60.
