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 24 with a mean of 52.2 and a standard deviation of 16.4 at a confidence level of 90%. 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.
