Suppose you fit the first-order model y = b0 + b1x1 + b2x2 + b3x3 + b4x4

Question:

Suppose you fit the first-order model y = b0 + b1x1 + b2x2 + b3x3 + b4x4 + b5x5 + e to n = 30 data points and obtain SSE = .33 R2 = .92

a. Do the values of SSE and R2 suggest that the model provides a good fit to the data? Explain.

b. Is the model of any use in predicting y? Test the null hypothesis H0: b1 = b2 = b3 = b4 = b5 = 0 against the alternative hypothesis Ha: At least one of the parameters b1, b2,

c, b5 is nonzero. Use a = .05.
