Question 1. Points possible: 1 Unlimited attempts. 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 19 with a mean of 56.8 and a standard deviation of 9.3 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.
