Express the confidence interval 77 % 1 5 % in interval form. Express the answer in decimal format (do not enter as percents).\fAssume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 151 with 60.9% successes at a confidence level of 95%. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Round final answer to one decimal placeIf n=100 and p (p-hat) = 0.71, construct a 99% confidence interval. Give your answers to three decimals.
