Conclusion We reject both null hypotheses, there is sufficient evidence that B2 and B3 differ from 0 We fail to reject both null hypotheses, there is insufficient evidence that B2 and B3 differ from 0. We reject both null hypotheses, there is insufficient evidence that B2 and 3 differ from 0. We fail to reject both null hypotheses, there is sufficient evidence that B2 and By differ from 0. Why would the outcome of each test help us determine whether or not a given variable should be used in the regression model? If a coefficient is found to be different from 0, then it does not contribute to the regression equation. If a coefficient is found to be different from 0, then it contributes to the regression equation. If a coefficient is found to be not different from 0, then it contributes to the regression equation. If a coefficient is found to be not different from 0, then it does not contribute to the regression equation. (f) Find a 90% confidence interval for each coefficient. (Use 2 decimal places.) lower limit upper limit B2 B3 < > (g) Suppose Michael is 68 years old and weighs 192 pounds. Predict his systolic blood pressure, and find a 90% confidence range for your prediction. (Use 1 decimal place.) prediction lower limit upper limit
