If X is a random variable that represents the weight of food cans produced by one of the Institutions, and X was a subject to a normal distribution of 150 grams, a sample size of 9 cans is taken from the production of this Institutions, and it is found that the standard deviation of the weights of these cans is equal to 5 grams. The probability that the mean of this sample exceeds 155 grams will be?

X is a random variable with moments E(X), E(X2), E(X3), and so forth. (a) Show E(X - )3 = E(X3) - 3[E(X2)][E(X)] + 2[E(X)]3. (b) Show E(X - )4 = E(X4) - 4[E(X)][E(X3)] + 6] E(X)]2[E(X2)] - 3[E(X)]4.

If X is a random variable with moment-generating function M(t), and Y is a function of X given by Y = aX + b, show that the moment generating function for Y is e^tbM(at).

If X is a random variable, then E(X - a) = E(X ) - a and E(aX ) = aE(X ) for any number a. Give intuitive justifications of these results
