In a Chi-Squared Test of a Contingency Table,the Value of the Test

question 12

True/False

In a chi-squared test of a contingency table,the value of the test statistic was $\chi$ ² = 15.652,and the critical value at $\alpha$ = .025 was 11.1433.Thus,we must reject the null hypothesis at $\alpha$ = .025.
