An article in the Los Angeles Times (Dec. 3, 1993) reports that 1 in 200 people carry the defective gene that causes inherited colon cancer. 2000 individuals were sampled. (a) Use Minitab to calculate the exact binomial probability that i) between 5 and 8 (inclusive) carry the gene. ii) at least 8 carry the gene. (b) Use normal approximation to calculate the approximate binomial probability that i) between 5 and 8 (inclusive) carry the gene. ii) at least 8 carry the gene. (c) In your opinion, is the normal approximation good for this problem?
