To test for independence between two categorical variables, we use a Chi-Square test. The critical value for a Chi-Square test with one degree of freedom at an alpha level of .05 is 3.8415. Therefore, if the calculated Chi-Square value is greater than 3.8415, we reject the null hypothesis of independence. Thus, the statement is true.
