Explanation / Answer

from above output:

A) regression equation: Y =15261.91594-1197.144603*Age+2253.540212*Dealer_indiv-43.22901734*Mileage

b)

95% confidence interval for age =-1790.155057 ; -604.1341495

95% confidence interval for Dealer_indiv =628.9097267 ; 3878.170697

95% confidence interval for mileage =-95.88866121 ; 9.43062653
