Find the margin of error M.E. that corresponds to a sample of size 136 with 64 successes at a confidence level of 99.9%. M.E. = % (report answer accurate to one decimal place; answer should be reported as a percent, not a decimal-though do not type the percent sign) Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
