Assume that a sample is used to estimate a population proportion μ . Find the margin of error M.E. that corresponds to a sample of size 408 with a mean of 39.1 and a standard deviation of 11.3 at a confidence level of 99.9%. Confidence Interval for Means Calculator Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may...
