Assume that a sample is used to estimate a population mean μμ. Find the margin of error M.E. that corresponds to a sample of size 20 with a mean of 82.1 and a standard deviation of 17.3 at a confidence level of 99.9%. 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.
