STOR 435 Handout 8 Sections 4.7-4.9 Note that we will be covering selected topics from these sections. The pages we will be covering are: Section 4.7: 143-146; Section 4.8: 155-157; 160-163; Section 4.9. Example 1 (Exercise 4.58 (c); Poisson distribution) . Compare the Poisson approximation with the correct binomial probability when n = 10 ,p = . 1 and you are trying to calculate P ( X = 0). Example 2 (Exercise 4.65(a)) . Each of 500 soldiers in an army company inde- pendently has a certain disease with probability 1 / (10) 3 . This disease will show up in a blood test, and to facilitate matters, blood samples from all 500 soldiers are pooled and tested. What is the (approximate) probability that the blood test will be positive ( that is, at least one person has the disease)? Example 3 (Exercise 4.55; Poisson distribution) . A certain typing agency em- ploys 2 typists. The average number of errors per article is 3 when typed by the Frst typist and 4.2 when typed by the second. If your article is equally likely
