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 24 with a mean of 38.8 and a standard deviation of 5.5 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.
