d$)$ Using model $($b$),$ predict the average fare on a route with the following characteristics: COUPON

$=1\mathrm{.}202,$ NEW $=3,$ VACATION $=$ No$,$ SW $=$ No$,$ HI $=4442\mathrm{.}141,$ S$\_$INCOME $=$ $$28,760,$ E$\_$INCOME

$=$ $$27,664,$ S$\_$POP $=4,557,004,$ E$\_$POP $=3,195,503,$ SLOT $=$ Free, GATE $=$ Free, PAX $=12,782,$

DISTANCE $=1985$ miles.

Remark: You do not need to implement this part in RapidMiner, you can use any tool $($e$.$g$.,$ Excel$)$

to calculate your prediction. Note that some coefficients in your regression equation might be

very small and rounded to zero. Copy and paste all coefficients directly from RapidMiner to Excel

because the small coefficient can be multiplied by large predictor values $($e$.$g$.,$ population$)$ and

can potentially have an effect which is not negligible
