Question:

Archery A champion archer can generally hit the bull’s-eye 80% of the time. Suppose she shoots 200 arrows during competition. Let p^ represent the percentage of bull’s-eyes she gets (the sample proportion).

1. What are the mean and standard deviation of the sampling distribution model for p^?

2. Is a Normal model appropriate here? Explain.

3. Sketch the sampling model, using the 68–95–99.7 Rule.
