A)$\chi$ 2 test for the difference in two proportions.
B)$\chi$ 2 test for independence.
C)a Z test for the difference in two proportions.
D)a t test for a correlation coefficient.

Quizplus · Accepted Answer

To determine if there is a linear relationship between two continuous variables, such as alcohol consumption and grade point average, a t test for a correlation coefficient is appropriate. This test assesses the significance of the Pearson correlation coefficient, which measures the strength and direction of a linear relationship between two variables.
