An Olympic archer is able to hit the bull's-eye 83% of the time. Assume each shot is independent of the others. She shoots 9 arrows. a) How many bull's-eyes do you expect her to get? b) What is the standard deviation? c) If she keeps shooting arrows until she hits the bull's-eye, how long do you expect it will take? (simply answers)

The archer in Exercise 18 will be shooting 200 arrows in a large competition. a) What are the mean and standard deviation of the number of bull’s-eyes she might get? b) Is a Normal model appropriate here? Explain. c) Use the 68–95–99.7 Rule to describe the distribution of the number of bull’s-eyes she may get. d) Would you be surprised if she made only 140 bull’s eyes? Explain.
