Use the table and the given regression equation to answer parts (a)-(e). 3 2 y=4-4x -8 X y 1 O No OYes 0 -4 a. Compute the three sums of squares, SST, SSR, and SSE, using the defining formulas. SST = (Type an integer or a decimal.) SSR= (Type an integer or a decimal.) SSE = (Type an integer or a decimal.) b. Verify the regression identity, SST = SSR + SSE. Is this statement correct? c. Determine the value of r2, the coefficient of determination. 2 (Round to four decimal places as needed.)
