1 if level 2 1 if level 3 MINITAB was used to fit the model below to n = 15 data points, where x1 = and x2 = . Complete parts a through d. 0 if not 0 if not y = Bo + B1 x1 + P2x2 + = Click the icon to view the MINITAB output. a. Report the least squares prediction equation. (Type integers or decimals.) b. Interpret the values of P, and B2- By estimates the difference in the mean value of the variable between level and the base level of the qualitative variable. By estimates the difference in the mean value of the variable between level | and the base level of the qualitative variable. c. Interpret the following hypotheses in terms of #1 . up, and #3. Ho: P1 = P2 = 0 Ha: At least one of the parameters , and Ply differs from 0. The hypothesis Ho: B, = P2 = 0 is the same as Ho: The hypothesis He: At least one of the parameters By and By differs from 0 is the same as He: d. Conduct the hypothesis test of part c. Use a= 0.05. What is the test statistic?d. Conduct the hypothesis test of part c. Use a = 0.05. What is the test statistic? The test statistic is (Type an integer or a decimal.) What is the p-value? The p-value is (Type an integer or a decimal.) What is the conclusion from the hypothesis test? O A. There is sufficient evidence to indicate x, is at level 2 about 95% of the time. O B. There is insufficient evidence to indicate at least one of the means is different at a = 0.05. O C. There is sufficient evidence to indicate xo is at level 3 about 95% of the time. O D. There is sufficient evidence to indicate at least one of the means is different at a = 0.05.
