Assume that a sample is used to estimate a population mean

. Find the margin of error M.E. that corresponds to a sample of size 22 with a mean of 29.2 and a standard deviation of 5.6 at a confidence level of 80%.

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.
