ssume 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 126 with 89.7% successes at a confidence level of 98%. M.E. = % Report answer accurate to one decimal place (as a number of percentage points). Answer should be obtained without any preliminary rounding (however, the critical value may be rounded to 3 decimal places).
