12.) Draw a density curve and use the calculator to determine the probability. Write the calculator function. 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 = 205 pounds and standard deviation = 15 pounds. Based on this information, what is the probability that all 49 boxes can be safely loaded onto the freight elevator and transported? 13.) Draw a density curve and use the calculator to determine the probability. Write the calculator function. Use the Normal approximation to Binomial to approximate the probability. Based on past experience a company determines that 7% of all luncheon vouchers are filled out incorrectly. If a random sample of 400 vouchers is selected, what is the approximate probability that at most 25 are filled out incorrectly? 12.)
