(a) What is the expected value of the total contents of a sample of 5 bags?
(b) What is the standard deviation of the total contents of a sample of 5 bags?
(c) What is the expected value of the mean contents of a sample of 5 bags?
(d) What is the variance of the mean contents of a sample of 5 bags?
(e) Assuming that the contents of the bags of salts are normally distributed. What is the probability that the mean contents of a sample of 5 bags will be less than 1 kg?
