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)...
