Use the table and the given regression equation to answer parts (a)-(e). 20 1 0 X y 3 -9 Yes No a. Compute the three sums of squares, SST, SSR, and SSE, using the defining formulas. SST = 42 (Type an integer or a decimal.) SSR = 40.5 (Type an integer or a decimal.) SSE 1.5 (Type an integer or a decimal.) b. Verify the regression identity, SST = SSR + SSE. Is this statement correct? - 3 c. Determine the value of r2², the coefficient of determination. (Round to four decimal places as needed.) y = 5-4.5x
