Unformatted text preview: Total 11 513.12 (a) (4 pts) Compute the SSE (Pure Error) and MSE (Pure Error) , and fill in the blanks. Hint: âˆ§ = = 2 2 ) ( Ïƒ s PureError MSE is the best estimate of the variance of Y at a given x. (0.5633+0.1600+0.1633+0.4433)/4 = 0.3325 (b) (3 pts) Is the linear relationship between the yield ( y ) and the temperature ( x ) significant at a 0.05 significance level? Why? Yes, because the P_value is very low. 0.000<0.05. (c) (3 pts) Is there any quadratic or higherorder relationship between y and x at a 0.05 significance level? Why? No, because the P_value is 0.224>0.05....
