Bob selects independent random samples from two populations and obtains the values pi 0.700 and p2 = 0.500. He constructs the 95% confidence interval for p1 – P2 and gets: 0.200 + 1.96(0.048) = 0.200 ±0.094. Note that 0.048 is called the estimated standard error of pi – p2 (the ESE of the estimate). - Tom wants to estimate the mean of the success rates:
