Which of the following correctly represents the equation for adjusted R²? A) ²= 1 - [SSR/(n -1)]/[SST/(n+1)] B) ²= 1 - [SSR/(n -k - 1)]/[SST/(n+1)] C) ²= 1 - [SSR/(n -k - 1)]/[SST/(n - 1)] D) ²= 1 - [SSR]/[SST/(n - 1)]

The formula for adjusted R-squared is represented as 1 - [SSR/(n-k-1)]/[SST/(n-1)], where SSR represents the sum of squared residuals, SST represents the total sum of squares, n is the number of observations, and k is the number of independent variables in the regression equation. The given equation includes ^,, ²^{, and}, which do not change the formula for adjusted R-squared. Therefore, the correct representation of the equation is C with the correct hexadecimal code.
