23 - It is desired to compare the end-of-term achievements of two faculty members who teach the same course. The success rate of A was 0.45 and the success rate of B was 0.56. Since the standard error of the difference between the rates is 0.038, find the confidence limits of the difference between the academic members' end-of-term success rates with a probability of 95%.
