Estimate a linear trend model and a quadratic trend model (Negative values should be indicated by a minus sign. Round your answers to 4 decimal places.) Linear Trend Intercept NA Adjusted R2 b-2. Which trend model describes the data well? Linear trend model based on the R2 measure. O Linear trend model based on the adjusted R2 measure. 0 Quadratic trend model based on the R2 measure. Quadratic trend model based on the adjusted R2 measure. Hints References eBook & Resources Hint#1 Check my work 3

Explanation / Answer

(b1)  

(b2) right choice is third and fourth

since R2 and adujusted R2 is more for quadratic trend, so quadratic is better

following information has been generated using ms-excel as linear and quadratic trend

variable linear quadratic intercept 12.3680 10.7922 t 0.2647 0.6945 t2 -0.0205 adjusted R2 0.4939 0.5560
