We modeled the price of a car using its mpg and its manufacturing site (foreign or domestic). the regression output is provided below. note that domestic is the reference level for manufacturing site, and that the data is somewhat old so the prices may seem too low for today's prices. what is the predicted price of a foreign car that gets 26 miles per gallon?
coef. std. err. t p(t > |t|)
intercept 11905 1159 10.27 0.000
mpg -294 55 -5.35 0.000
site: foreign 1767 700 2.52 0.014
a. 6028
b. 4261
c. 19549
d. 21316
