Assume that a sample is used to estimate a population mean μ. Find the margin of error M.E. that corresponds to a sample of size 707 with a mean of 66.8 and a standard deviation of 8.2 at a confidence level of 99.8%. 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 be rounded to 3 decimal places.
