Suppose That Independent Variable a Explains 24 Percent of the Variation

Multiple Choice

A) The partial r for variable B is .10.
B) The multiple correlation between both variables and the dependent variable is .50.
C) Multicollinearity exists between the two independent variables.
D) All of these.
