Problem 5. How many ways can you select a committeo of 5 persous from a group of 100 persons? The order in which the persons are chosen does not matter. You collect a random sample of 28 observations from a normally distributed population with unknown mean and unknown standard deviation. Your sample mean is 5.13 , and your sample standard deviation is 1.47 . What is the upper bound of your 95% confidence interval for the population mean? Round your answer to two decimal places.
