a. Complete the ANOVA table.
b. Conduct a global test of hypothesis, using the .05 significance level. Can you conclude that any of the net regression coefficients are different from zero?
c. Conduct a test of hypothesis on each of the regression coefficients. Could you delete any of the variables?
