Let X₁, X₂,... denote an iid sequence of random variables, each with expected value 75 and standard deviation 15. (a) How many samples n do we need to guarantee that the sample mean M_n(X) is between 74 and 76 with probability 0.99?

(b) If each X_i has a Gaussian distribution, how many samples n' would we need to guarantee M_n (X) is between 74 and 76 with probability 0.99?
