\fd. Fit the model from part a to the data, using an available statistical software package. Is the overall model statistically useful in predicting lead level? Test. using a = 0.10. What is the fitted model? O A. The fitted model is y = 2.632 + 0.000471x, - 3.490x2 + 0.002430* *2- O B. The fitted model is y = 0.000471 + 2.832x1 - 3.490x2 + 0.002430x1*2. O C. The fitted model is y = 2.832 + 0.000471x1 - 3.490*2- Set up the null and alternative hypotheses to determine if the overall model is statistically useful. Choose the correct answer below. O A. Ho: By = By = P3 = 0 versus He: At least one ; # 0, i= 1, 2, 3. O B. Ho: At least one ( # 0, i= 1, 2. 3 versus Ha: Py = P2 = 13 =0. O C. Ho: Bg =0 versus Hy: Bg = 0. What is the test statistic? The test statistic is (Round to two decimal places as needed.) What is the p-value? The p-value is (Round to three decimal places as needed.)\fX Data table Specimen Lead level Elevation Slope face 3.485 2.000 3.359 2.000 3.877 2,000 4.000 2.500 3.618 2,500 5.413 2.500 7.181 2,500 6.589 2.500 6.182 2.000 10 3.706 2.000 Print Done
