question 7

The following information summarizes the linear relationship between the age (in years) and measured carbon dioxide emissions (in g/km) of vehicles in the U.S. based on a random sample of 129 vehicles. All vehicles sampled were between 0 and 59 years old. You may take for granted that all requisite assumptions for this dataset are satisfied. Simple linear regression results: CO2 - 132.37 + 2.91Age Sample Size: 129 R - 0.8372 R2 - 0.7009 Parameter estimates: Parameter Estimate Std. Err. Alternative DF T-Stat P-value Intercept ??? 3.01 ?? ??? ??? Slope ??? 1.18 #0 ? ? ??? ??? Calculate the test statistic necessary to test whether or not there is a statistically significant linear relationship between vehicle age and carbon dioxide emissions, round your answer to two digits past the decimal place
