Question
A shoe store developed the following estimated regression equation relating sales to inventory investment and advertising expenditures.
ý = 23 + 12x, + 6x2
where
x, = inventory investment ($1,000s)
X2 = advertising expenditures ($1,000s)
y = sales ($1,000s).
(a) Predict the sales (in dollars) resulting from a $14,000 investment in inventory and an advertising budget of $11,000.
(b) Interpret b, and b, in this estimated regression equation.
Sales can be expected to increase by $
for every dollar increase in inventory investment when advertising expenditure is held constant. Sales can be
expected to increase by $
for every dollar increase in advertising expenditure when inventory investment is held constant.
