Question 1157637: 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 10 with a mean of 25.5 and a standard deviation of 6.3 at a confidence level of 99.5%.

margin of error is t(0.9975,df=9)*s/sqrt(n)
=3.69*6.3/sqrt(10)
=7.35 units
