According to an expert for the airline industry, 11% of Americans are afraid to fly. Suppose 1200 Americans are sampled. (Give results accurate to at least 4 decimal places.) a. Of the 1200 people sampled, 149 respond that they are afraid to fly. What is the sample statistic p? p = b. Under the assumption that the industry expert's claim that 11% of Americans are afraid to fly is valid, what is the probability that the survey in part (a) would result in a p that is same or lower as the one found? c. Under the assumption that the industry expert's claim that 11% of Americans are afraid to fly is valid, what is the probability that the survey in part (a) would result in a p that is between 9% and 12%?
