Name__________________________. Due Friday, February 13.
1. Do Exercise 5.26 on page 191.
2. (Like Ex. 5.30 page 191). A judge is scheduled to hear 20 appeals for traffic tickets. Each appeal has a probability of .25 of being approved, independent of the other appeals. Find the probability that the number of appeals approved is no less than 3 and no more than 7, i.e., between 3 and 7 inclusively. First do this exactly, using Table A1. Next use the normal approximation to the binomial. Compare the two answers.
3. Replace the probability function of Exercise 5.40 on page 219 with f(1) = .25 = f(5), f(2) = .2 = f(4), f(3) = .1. With this probability function do exercise 5.40 on page 219.
4. Using the probability function in problem 3 above, do exercise 5.41 on page 219.
5. Using the probability function in problem 3 above, do exercise 5.42 on page 219.
6. Using the probability function in problem 3 above, do exercise 5.43 on page 2.19.
