Regressions were performed on measurements, x and y, taken on 8 subjects. Regression 1 produced ŷ = 57.1024 + 17.331x and had the residual plot:

Regression 2 produced square root of y hat. = 0.158283 + 0.98559 x and had the residual plot:

Which statement is best supported by the evidence?

Select one:

a. Regression 1 is a better fit as there is a linear relationship between x and y.

b. Regression 2 is a better fit as there is a linear relationship between x and y.

c. There is a positive relationship between x and y.

d. Regression 1 is a better fit as there is a nonlinear relationship between x and y.

e. Regression 2 is a better fit as there is a nonlinear relationship between x and y.
