Question
Management proposed the following regression model to predict sales at a fast-food outlet.
y Bo+P +Bzs + Bzy +e
where
#1=number of competitors within one mile
= population within one mile (1000s)
1 f drive-up whdow present
0 otherwise
y= sales ($1000s)
The following estimated regression equation was developed after 20 outlets were surveyed.
ý = 10.2 – 4.7z + 6.9z + 15.1S
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 9,000 within one mile, and no drive-up window.
Estimate of sales = $
c. Predict sales for a store with one cormpetitor, a population of 3,000 within 1 mile, and a drive-up winndow.
Estimate of sales =$
