Data on the average annual precipitation (y), altitude (x), latitude (x), and distance from the coast (x3) for a particular state were collected fo meteorological stations. The observations are listed in the table below. Consider the first-order model y = Po + BX + Bx + 3x3 + E. Complet parts a through c. Station 2 3 4 y (in) 40.12 23.45 18.65 38.40 49.64 x (ft) 45 340 4155 71 6757 x () 44.6 40.3 34.0 39.2 39.4 a. Fit the model to the data and give the least squares prediction equation. y = -113.692 + (005) x + (3.560 ) x + (-080) x3 (Round to three decimal places as needed.) A. Ho: B B B3 = 0 H B B B3 #0 B.

(Round to two decimal places as needed.) Station 67890 10 b. Is there evidence that the first-order model is useful for predicting annual precipitation y? Test using a = 0.05. Determine the null and alternative hypotheses. Choose the correct answer below. y (in) 20.44 17.82 13.99 41.28 14.75 The p-value is .007 (Round to three decimal places as needed.) Is there evidence that the first-order model is useful for predicting annual precipitation y? Yes, because the p-value is less than a = 0.05. c.
