A random sample of n measurements was selected from a population with unknown mean μ and standard deviation o=15 for each of the situations in parts a through d. Calculate a 99% confidence interval for µ for each of these situations. a. n = 60, x=28 b. n = 200, x= 108 c. n = 80, x= 14 d. n=80, x= 4.09 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. a. (Round to two decimal places as needed)
