Question
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
5 with a mean of 67.1 and a standard deviation of 7.2 at a
confidence level of 90%.
Report ME accurate to one decimal place because the sample
statistics are presented with this accuracy.
М.Е.
%3D
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
