Ten percent of Americans are allergic to ragweed. Suppose a random sample of 200 people is selected. 1. Identify n 2. Identify p (Round to 2 decimal places) 3. Identify 1 - p (Round to 2 decimal places) 4. Evaluate np and n(1 - p). Is it appropriate to use the normal distribution to approximate the binomial distribution? (Round to 2 decimal places) np = n(1 - p) = Enter Y or N If your answer to part (d) above is "yes" answer the following questions. 5. What is the mean and standard deviation of the approximationg normal distribution? (Round to 2 decimal places) H = O=
