Let X equal the weight of the soap in a "6-pound" box. Assume that the distribution of X is N(6.05, 0.0004). a) Find P(X < 6.0171). b) If nine boxes of soap are selected at random from the production line, find the probability that at most two boxes weigh less than 6.0171 pounds each. HINT: Let Y equal the number of boxes that weigh less than 6.0171 pounds. c) Let Xbar be the sample mean of the nine boxes. Find P(Xbar ≤ 6.035).
