Extracted text: 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 23 with a mean of 50.7 and a standard deviation of 20.2 at a confidence level of 99.9%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. М.Е. — Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
