Answer:
y [ Expected Sales ] = 20.62 thousands
Step-by-step explanation:
Regression line : y = 14.8 − 3.5x1 + 3.2x2 + 15.8x3 ; where
y = sales (in 1000s), x1 = number of competitors within one mile, x2 = population (in 1000s) within one mile, x3 = 1 (if a drive-up window is present) or x3 = 0 (if a drive-up window is not present)
x1 (competitors) = 3 , x2 (population) = 5100 = 5.1 thousands , x3 (no drive up window) = 0
y = 14.8 − 3.5 (3) + 3.2 (5.1) + 15.8 (0)
y = 14.8 - 10.5 + 16.32
y [ Expected Sales ] = 20.62 thousands
If I am correct, the answer should be D. If you need further explanation, I can supply you with that as well.
