Final answer:
The answer cannot be determined without knowing the values of SSR and SST.
Step-by-step explanation:
The variance in the dependent variable that can be explained by the variance in the independent variable is measured by the coefficient of determination, also known as R-squared. R-squared is calculated by dividing the sum of squares for regression (SSR) by the total sum of squares (SST). Therefore, the answer to the question cannot be determined without knowing the values of SSR and SST.
