The coefficient of determination (R^2) is .12, which means that 12% of the variance in the dependent variable is explained by the model. Given that the total sum of squares (SST) is 225, the sum of squares regression (SSR) can be found by multiplying the total sum of squares by the coefficient of determination: SSR = R^2 * SST = .12 * 225 = 27.
