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 15 with a mean of 29.3 and a standard deviation of 5.8 at a confidence level of 80%.
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.
