A statistics student wanted to determine if the distance to a destination was related to the price an airline would charge to fly to that destination. The student did a regression of airfare, y, on distance, x, and obtained the printou shown below from a statistical software package. Predictor Coef Constant 83.02 Distance 0.117 SE Coef 49.29 0.028 Oŷ= 0.117 + 83.02x Oy=83.02 +0.117x Oŷ= 49.29 + 83.02x Oŷ= 0.028+ 0.117x Oŷ=83.02 + 25.25x t-ratio 1.689 4.179 S = 25.25 R-Sq = 63.2% R-Sq (Adj) Which of the following is the correct equation of the least-squares line?
