Assume that a sample is used to estimate a population mean μμ. Find the margin of errorM.E. that corresponds to a sample of size 19 with a mean of 71.6 and a standard deviation of 9.3 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.
