III. HOME WORK PROBLEMS

10. SAMPLE SIZE

This is a problem of determining how "representative" is 1,000 samples in capturing an arbitrary distribution.
  1. What is the probability that none of the 1,000 samples lie in the top-1% of the population?

  2. What is the probability that at least n (< 20) of the 1,000 samples lie in the top-1% of the population (you expect on the average 10 samples will lie in the top-1%)?
