Assume that a sample is used to estimate a population proportion .
Find the margin of error M.E. that corresponds to a sample of size
73 with a mean of 78.7 and a standard deviation of 10.4 at a confidence level of 98%.
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.
