A random sample of n measurements was selected from a population with unknown mean mu and standard deviation sigmaequals15 for each of the situations in parts a through d. Calculate a 95% confidence interval for mu for each of these situations.
a. nequals50, x overbarequals39
b. nequals200, x overbarequals104
c. nequals110, x overbarequals16
d. nequals110, x overbarequals5.54
e. Is the assumption that the underlying population of measurements is normally distributed necessary to ensure the validity of the confidence intervals in parts a through d? Explain.
