S_.docx-AAn elevator has a placard stating that the maximum capacity is 2400 lb-15 passengers. So, 15 adult male passengers can have a mean weight of up to 2400/15 = 160 pounds. If the elevator isloaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 160 lb. (Assume that weights of males are normally distributed with amean of 169 lb and a standard deviation of 31 lb.)

Suppose that all the students registered to the probability and statistics course have to buy textbook. The 28 % of all students demand a new book, on the other hand the other 72 % want a used text book. Consider randomly selecting 40 purchasers.a. What are the mean value and standard deviation of the number who want a new copy of thebook?b. What is the probability that the number who want brand-new books is more than 1.5σ awayfrom the mean value?c. The bookstore has 30 new and 30 used textbooks in stock. If 40 people come in one by one topurchase this text, what is the probability that all 40 will get the type of book they want fromcurrent stock? [Hint: Let X = the number who want a new copy. For what values of X will all 40get what they want?]
At a college the scores on the chemistry final exam are approximately normally distributed, with a mean of 73 and a standard deviation of 11. The scores on the calculus final are also approximately normally distributed, with a mean of 78 and a standard deviation of 12.
