(a) Make a power model for weight versus height. (Round the regression parameters to two decimal places.)
W = 0.22 x h1.38
w = 0.44 x h1.38
w = 0.11 x h2.38
W = 0.22 x h2.38
Ow = 0.44 x h2.38
(b) According to the model from part (a), what percentage increase in weight can be expected if height is increased by 11%? (Round your answer to the nearest whole number.)
