Let x1, x2, . . . ,
x100 denote the actual net weights (in pounds)
of 100 randomly selected bags of fertilizer. Suppose that the
weight of a randomly selected bag has a distribution with mean 25
lb and variance 1 lb2. Let x be the sample mean
weight (n = 100).
(a) What is the probability that the sample mean is between
24.75 lb and 25.25 lb? (Round your answer to four decimal
places.)
P(24.75 ≤ x ≤ 25.25) =
(b) What is the probability that the sample mean is greater than 25
lb?

Let x1, x2, x3,...,x100 denote the actual weights of 100 randomly selected bags of fertilizer. Let X be the average weight of this sample. If the expected weight of each bag is 50 lb. and the standard deviation of bag weights is known to be 1 lb., calculate the approximate value of P (49.75 ≤ X ≤ 50.25).
