Part 1 of 2
(a) To construct a confidence interval for the mean, what method is appropriate here?
Z method, because we have the population standard deviation.
T method, because we have the sample standard deviation.
Neither method is appropriate, since the sample size is too small and we do not know if the population is approximately normal.
