1) Suppose a scheduled airline flight must average at least 0.60 occupancy in order to be profitable to the airline. An examination of the occupancy rate for 120, 6:00am flights from Atlanta to Dallas showed a mean occupancy per flight of 0.58 and a standard deviation of 0.11. a) If u is the mean occupancy per flight and if the company wishes to determine whether not this scheduled flight is profitable, give the alternate and null hypothesis. H.: H.: b) Is this a one tail or two tail test? c) What is the test statistic and critical value? d) Do the occupancy data for the 120 flights suggest that this scheduled flight is profitabl Test using a = 0.05
