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
221 with 27.1% successes at a confidence level of 99.9%.
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).
