Question #2 A consumer research firm wants to compare three brands of (Goodyear, Yokohama, and Michelin) in terms of tread life over diffe road surfaces. Random samples of four tires of each brand are selected each of three surfaces (asphalt, concrete, gravel). A machine that simulate road conditions for each of the road surfaces is used to find read life (in thousands of miles) of each tire. Construct a table conduct tests for the presence of nonzero brand effects, road sur effects, and interaction effects.

A consumer research firm wants to compare three brands of tires
(Goodyear, Yokohama, and Michelin) in terms of tread life over different
road surfaces. Random samples of four tires of each brand are selected for
each of three surfaces (asphalt, concrete, gravel). A machine that can
simulate road conditions for each of the road surfaces is used to find the
tread life (in thousands of miles) of each tire. Construct a table and
conduct tests for the presence of nonzero brand effects, road surface
effects, and interaction effects.
