$\text { Figure } 6.1$
-Based on the estimates in Figure 6.1,you should conclude that

• A)the regression function is overall statistically significant because 3.6997E - 22 < .05.
• B)the regression function is overall statistically insignificant because 3.6997E - 22 < .05.
• C)the regression function is overall statistically insignificant because .4739 > .05.
• D)the regression function is overall statistically significant because 2.4135E - 09 < 0.05.
