Question: Suppose that you fit the model E(y) = 0 + 1x1 + 2x2 + 3x3 to 15 data points and found F equal to 57.44.

Suppose that you fit the model
E(y) = β0 + β1x1 + β2x2 + β3x3
to 15 data points and found F equal to 57.44.
a. Do the data provide sufficient evidence to indicate that the model contributes information for the prediction of y? Test using a 5% level of significance.
b. Use the value of F to calculate R2. Interpret its value.
