Dr. Fauci provides you with a re-estimated model to test whether or not state income and the percent of the population under the poverty line are jointly significant in explaining state mortality. He wants a formal test. Model 1: OLS estimates using the 51 observations 1-51 Dependent variable: MORT Heteroskedasticity-robust standard errors, variant HC1 coefficient std. error t-ratio p-value const 525.484 52.6521 ????? 4.33e-013 6 HS -509.713 71.6409 ????? 6.13e-09 College -284.812 290.801 ????? 0.3325 Expenditures 0.114296 0.0192201 ????? 3.48e-07 Age>65 4378.30 299.575 ????? 6.65e-019 Mean dependent var 855.0059 S.D. dependent var 137.9660 Sum squared resid 89989.06 S.E. of regression 44.22990 R-squared 0.905447 Adjusted R-squared 0.897225 F(4, 46) 141.3803 P-value(F) 3.19e-25 Log-likelihood -262.9941 Akaike criterion 535.9882 Schwarz criterion 545.6474 Hannan-Quinn 539.6793 F. Calculate the correct test statistic for the joint test. (4 point) G. What is its critical value? (3 point) H. Is there sufficient evidence to reject the test that income and percent of the population under the poverty line are jointly significant in state mortality variation? (4 point)
