The fraction by which the variance of the dependent variable is greater than the variance of the errors is known as R-squared. The correct option is C, 0.32.
<h3>What is R- Squared?</h3>The fraction by which the variance of the dependent variable is greater than the variance of the errors is known as R-squared.
It is called so because it is the square of the correlation between the dependent and independent variables, which is commonly denoted by “r” in a simple regression model.
fraction of the variability in data values = (coefficient of correlation)² = r²
For the given data, the correlation can be found as shown below. Therefore, the value of r is -0.56. Since we need the value of r², the value of r² is,
r² = (-0.56)²
r² = 0.3136 ≈ 0.32
Hence, the correct option is C, 0.32.
