Assume 85% of people actually show up for thier flight on time. Because of this, airlines tend to overbook flights. A random sample of 201 booked passengers is taken and whether or not they showed up on time is recorded for each of them. a.) List the given information with the correct symbols: -85% OX OX Op ON Op Oo OH On Os = 201 On Op ON Op OH OX OX Os Oab. ) Can we say that the sampling distribution of p is approximately normal? Yes v Because np = which is ? v n(1 - p)= which is ? v and N - which is (or is assumed to be) ? v Note: if N is unknown, type 100000 in for its value. c.) What is the probability that at least 90% of them showed up on time? Fill in below with the correct random variable and inequality symbol in the probability statement. Round final answer to 4 decimal places. P( p v 80% is an unusually low percentage of on time booked passengers in a sample of 201 What might you conclude about the population if you observe a sample percentage this low? There is evidence that the percentage of booked passengers who are on time is now higher than 85% Submit
