The confidence levels are 9090. 95%, and 995%. and the intervals are (0,402, 0.598) (0:371 0 629), and (0.418. 0,582), Match such interval with its confidence level (a) The 95% confidence interval is (0 418, 0.582) (b) The 90% confidence interval is (0.371 0.629). (c) The number of successes will he needed to determine which interval matches which confidence level. (d) The 99% confidence interval is (0.371,0.629); 36.
