a. Write the equation of a​ straight-line model relating driving accuracy​ (y) to driving distance​ (x). Choose the correct answer below.

A. y=β1x

B.y equals beta 1 x squared plus beta 0y=β1x2+β0

C.y equals beta 1 x plus epsilony=β1x+ε

D.y equals beta 0 plus beta 1 x plus epsilony=β0+β1x+ε

Your answer is correct

.b. Fit the​ model, part a​, to the data using simple linear regression. Give the least squares prediction equation.Modifying

Above y with carety=(250.3) plus+ left parenthesis negative 0.6587 right parenthesis(−0.6587) xc.

Interpret the estimated​ y-intercept of the line. Choose the correct answer below.

A.Since a drive with​ 0% accuracy is outside the range of the sample​ data, the​ y-intercept has no practical interpretation.

B.For each additional yard in​ distance, the accuracy is estimated to change by the value of the​ y-intercept.

C.For each additional percentage in​ accuracy, the distance is estimated to change by the value of the​y-intercept.

D.Since a drive with distance 0 yards is outside the range of the sample​ data, the​ y-intercept has no practical interpretation.
