Problem
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 18 with a mean of 28.9 and a standard deviation of 21.4 at a confidence level of 99.5%. 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
The response should include a reference list. Using double-space, Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
