Assume that a sample is used to estimate a population proportion μ. Find the margin of error M.E. that corresponds to a sample of size 17 with a mean of 40.3 and a standard deviation of 7.8 at a confidence level of 99%.
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.
