Ten percent of Americans are allergic to ragweed. Suppose a random sample of 200 people is selected. If possible, use the normal approximation to find the probability that less than 10 will be allergic to ragweed. Use your mean and standard deviation calculated previously and rounded to two decimal places (questions 7 & 8) to calculate z-scores whenever needed. If it is not possible to use the normal approximation to the binomial, enter NA as your answer to this question.
