y^ = 0.9 - 0.3x
x: 2 5 1 4
y: 1 2 1 -4
a. Compute the three sums of squares, SST,
SSR, and SSE, using the defining formulas.
SST
SSR
SSE
b. Verify the regression identity, SST = SSR
+ SSE. Is this statement correct?
c. Determine the value of r squared
(Round to four decimal places.)
d. Determine the percentage of variation in the
observed values of the response variable that is explained by the
regression....
