Show that E[X 2] = 600 and find the value of E[X 3]. 4 Consider a random sample of size 16 taken from a normal distribution with mean = 25 and variance 2 = 4. Let the sample mean be denoted X . State the distribution of X and hence calculate the probability that X assumes a value greater than 26. 5 [3] [3]
