Of the 1100 people sampled, 157 respond that they are afraid to fly. What is the sample statistic p? p= 0.1427 b. Under the assumption that the industry expert's claim that 12% 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 12% 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 11% and 13%?
