Assume that a sample is used to estimate a population mean

. Find the margin of errorM.E.that corresponds to a sample of size 16 with a mean of 29.2 and a standard deviation of 18.6 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.=______________
