Assume 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 295 with 78% successes at a confidence level of 99.5%. 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 place
