Airline Occupancy Rates Suppose a scheduledairline flight must average at least 60% occupancyin order to be profitable to the airline. An examinationof the occupancy rate for 120 10:00 A.M. flightsfrom Atlanta to Dallas showed a mean occupancy perflight of 58% and a standard deviation of 11%.a. If m is the mean occupancy per flight and if thecompany wishes to determine whether or not thisscheduled flight is unprofitable, give the alternativeand the null hypotheses for the test.b. Does the alternative hypothesis in part a imply aone- or two-tailed test? Explain.c. Do the occupancy data for the 120 flights suggestthat this scheduled flight is unprofitable? Test usinga .05.
