We are interested in determining what type of model best describes the relationship between two variables x and y.
a.For a given data set, an estimated regression equation relating x and y of the form was developed, using Excel. The results are shown below. Comment on the adequacy of this equation for predicting y. Let = .05.
b.An estimated regression equation for the same data set (as in part a) of the form was developed. The Excel output is shown below. Comment on the adequacy of this equation for predicting y. Let = .05.
c.Use the results of Part b and predict y when x = 4.
