Assume that a sample is used to estimate a population mean u. Find the margin of error M.E. that
corresponds to a sample of size 18 with a mean of 80.8 and a standard deviation of 17.2 at a
confidence level of 99%.
Report ME accurate to one decimal place because the sample statistics are presented with this
аccuracy.
М.Е. %3
Answer should be obtained without any preliminary rounding. However, the critical value may be
rounded to 3 decimal places.
