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
17 with a mean of 29.2 and a standard deviation of 18.9 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.
