Assume that a sample is used to estimate a population proportionp. Find the margin of errorM.E. that corresponds to a sample of size 278 with 70.9% successes at a confidence level of 99%.



M.E. = %


The answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. The round final answer to one decimal place
