Question

Commercial airlines need to know the operating cost per hour of flight for each plane in their fleet. In a study of the relationship between operating cost per hour and number of passenger seats, investigators computed the regression of operating cost per hour on the number of passenger seats. The 12 sample aircrafts used in the study included planes with as few as 216 passenger seats and planes with as many as 410 passenger seats. Operating cost per hour ranged between $3600 and $7800. The summary of the data are shown below. Number of Passenger Seats Operating Cost Per Hour Mean 342 5112 Standard Deviation 57 1110 r 0.712 What is the equation of the least squares regression line that describes the relationship between operating cost per hour and number of passenger seats on a plane? Show all calculations using the equation editor. Find each value to the nearest cent. Be sure to use the "hat" over your y-variable name.
