2. Using the t statistic and appropriate critical values, test Ho : Bj = 0versus Ha : Bj ? 0 by setting a equal to .05.Which independent variables are significantly related to y in the model with a= .05?

3.Using the t statistic and appropriate critical values, test Ho : Bj = 0versus Ha : Bj ? 0 by setting a equal to .01.Which independent variables are significantly related to y in the model with a= .01?

4. find the p value for testing H_o: B_j = 0 versus H_a : B_j ? 0 on the output.Using the p value, determine whether we can reject H_o by setting a equal to .10, .05, .01, and .001.what do you conclude about the significance of the independent variables in the model?

5.calculate the 95% confidence interval for B_j and discuss one practical application of this interval

6. calculate the 99% confidence interval for B_j
