a manufacturer produces 25- pound lifting weights. the lowest actual weight is 24 pounds, and the highest is 26 pounds. each weight is equally likely so the distribution of weights is uniform. a sample of 100 weights is taken.
a) find the probability that the mean actual weight for the 100 weights is greater then 25.2
b) find the 90th percentile for the mean weight for the 100 weights

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)...

5. A large freight elevator can transport a maximum of 9800 pounds. Suppose a load of cargo containing 49 boxes must be transported via the elevator. Experience has shown that the weight of boxes of this type of cargo follows a distribution with mean u = 205 pounds and standard deviation o = 15 pounds. Based on this information, what is the probability that all 49 boxes can be safely loaded onto the freight elevator and transported? A study involving...
