Use the table and the given regression equation to answer parts (a)-(e). 3 1 20 y=-1-x -2 0 x y a. Compute the three sums of squares, SST, SSR, and SSE, using the defining formulas. SST = -7 (Type an integer or a decimal.) (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? SSR= No Yes c. Determine the value of r², the coefficient of determination. 2=(Round to four decimal places as needed.)
