1. Principal, Joo Siloocy, is planning a school fieldtrip for all 450 students. As usual, she is planning to bring snacks. Over time she has established that only 70% of kids will take the snack that they are offered. The rest will refuse because of food allergies, dietary restriction, or simplify having a horrible attitude. In particular she wants know, if she packs 340, what are the chance that will be short? a. Define the random variable and give the range of possible values. b. Is the use of normal approximation appropriate? Justify your answer. c. What are values of A & a? d. CCF? e. Z interval. f. Final answer? 2. 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 = 14 pounds. Based on this information, what is the probability that all 49 boxes can be safely loaded onto the freight elevator and transported? (hint: in particular each box on the average should weigh less than 200 pounds for this to happen.) a. What is the shape of distribution for the average weight of the boxes. b. What is He = ?_ c. What is of = ? d. Final answer for probability of
