Two of the airlines did not have an airline quality score. The least-squares regression line for this data is given by ŷ = 0.990 + 0.683 x. (Let x = passenger complaint rank and y = airline quality score.) Use the least-squares line to predict the airline quality score for Hawaiian Airlines and Northwest Airlines. (Round your answers to three decimal places.)

Answer:

Step-by-step explanation:

the passengers of  hawaiian airlines  in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)

We replace this number in the equation :

Hawaiian : 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (1.800.000) =12294012

Northwest airlines: 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (195.000.000) = 131477501
