I need this answered, for each part please

A random sample of n measurements was selected from a population with unknown mean u and standard deviation o = 35 for each of the situations in parts a through d. Calculate a 99% confidence interval for u for each of these situations. a. n= 60, x = 28 b. n = 150, x = 108 c. n = 125, x = 16 d. n = 125, x = 5.67 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
