1. A box contains twelve tickets, labeled with the numbers 5, 7, 10, 12, 14, 16, 24, 29, 33, 38, 39, 45.The normal approximation to the chance that the sum of 60 draws with replacement from this box is no larger than 1657 is?
2. A box contains 100 tickets labeled with numbers. None of the labels is negative. The average of the labels is 91.8. Eight tickets will be drawn independently at random with replacement from the box.The chance that the sample sum exceeds 5801.76 is?
