Calculate the single-sided upper bounded 90% confidence interval
for the population mean (mu) given that a sample of size n=19
yields a sample mean of 11.26 and a sample standard deviation of
3.39.
For the following PAIRED OBSERVATIONS, calculate the 95%
confidence interval for the population mean mu_d: A = {8.77, 6.86,
9.92, 8.46}, B = {3.70, 3.06, 5.33, 5.45}.
For the following PAIRED OBSERVATIONS, calculate the 90%
confidence interval for the population mean mu_d: A = {13.34, 9.49,
10.49, 11.43, 11.86}, B = {6.87, 5.95, 6.30, 7.97, 5.79}.
