You have just computed a regression in which the value of coefficient of multiple determination is 0.57.To determine if this indicates that the independent variables explain a significant portion of the variation in the dependent variable,you would perform an F test.

The coefficient of multiple determination (R-squared) measures the proportion of the variation in the dependent variable that is explained by the independent variables in a regression model. However, it does not indicate whether the explained variation is statistically significant. To determine if the independent variables have a significant effect, an F test is typically used to compare the regression model to a null model (e.g., one that only includes an intercept term). Thus, the statement that an F test should be performed to determine if the independent variables explain a significant portion of the variation in the dependent variable is true.
