Management proposed the following regression model to predict
sales at fast food outlet. ? = ?0 + ?1?1 + ?2?2 + ?3?3 + ? where ?1

????(1000?) ?3 = { 1 ?? ???? − ?? ?????? ??????? 0 ??ℎ?? ???? ? =
????? ($1000?) The following estimated regression equation was
developed after 20 outlets were surveyed. ?̂ = 20.2 + 3.2?1 + 5.8?2
+ 25.7?3 a. What is the expected amount of sales attributable to
the drive-up window? b. Predict sales for a store with two
competitors, a population of 2000 within one mole, and no dive-up
window. c. Predict sales for a store with two competitors, a
