Suppose you fit the first-order model to n = 30 data points and obtain SSE = .33

Question:

Suppose you fit the first-order model 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 H,,: P1 = P2 = P3 = P4 = P5 = 0 against the alternative hypothesis Ha: At least one of the parameters PI, P2, . . ., Ps is nonzero. Use (Y = .05.
