Suppose You Estimate the Sample Regression Function $$\log ( \text { Solar } \widehat {Syst}em \text { Sales} ) = 108,632.47 - 3.78 \cdot \log ( \text { Solar System Tax Rate } )$$

Multiple Choice

Suppose you estimate the sample regression function $$\log ( \text { Solar } \widehat {Syst}em \text { Sales} ) = 108,632.47 - 3.78 \cdot \log ( \text { Solar System Tax Rate } )$$
You should conclude that a

A) $1 increase in the solar system tax rate is associated with 3.78 fewer solar system sales.
B) 1 percent increase in the solar system tax rate is associated with a 3.78 percent decrease in solar system sales.
C) 1 percent increase in the solar system tax rate is associated with 3.78 fewer solar system sales.
D) $1 increase in the solar system tax rate is associated with a 3.78 percent decrease in solar system sales.
