- To estimate the mean of a population with unknown
distribution shape and unknown standard
deviation, we take a random sample of size 64. The sample
mean is 22.3 and the sample standard deviation is 8.8. If we wish
to compute a 92% confidence interval for the
population mean, what will be the t multiplier? (Hint: Use
either a Probability Distribution Graph or the Calculator from
Minitab.)
