$\text { Figure } 5.2$
-Based on the Excel output in Figure 5.2,you should conclude that the estimated slope coefficient is

• A)statistically significant because -8.076 < .05.
• B)statistically significant because -0.466 < .05.
• C)statistically significant because |-8.076| > 1.96.
• D)statistically insignificant because -0.466 is inside the 95% confidence interval.
