Assignment:
Use the given data to find the best predicted value of the response variable. Be sure to follow the prediction procedure summarized in Figure below.
Supermodel Heights and Weights Heights (in inches) and weights (in pounds) are obtained from a random sample of nine supermodels (Alves, Avermann, Hilton, Dyer, Turlington, Hall, Campbell, Mazza, and Hume). The linear correlation coefficient is 0.360 and the equation of the regression line is ˆy= 31.8 + 1.23x, where x represents height. The mean of the nine heights is 69.3 in. and the mean of the nine weights is 117 lb. What is the best predicted weight of a supermodel with a height of 72 in.?
