If you wanted to find out if alcohol consumptions (measured in ml)and grade point average on a four-point scale are linearly related,you would perform a A) χ² test for independence. B) Z test for the difference in two proportions. C) χ² test for the difference in two proportions. D) t test for a correlation coefficient.

To determine if there is a linear relationship between two continuous variables, we need to use a correlation coefficient. The t test for a correlation coefficient is specifically designed for testing the significance of correlations between two variables. Therefore, option D is the best choice to test the linear relationship between alcohol consumption and grade point average.
