To determine whether four populations are equal, a sample from each population was selected at random and using the Kruskal-Wallis test, H was computed to be 2.09. What is our decision at the 0.05 level of risk? Fail to reject the null hypothesis because 0.05 < 2.09 Fail to reject the null hypothesis because 2.09 < 7.815 Reject the null hypothesis because 7.815 is > 2.09 Reject the null hypothesis because 2.09 > critical value of 1.96 None of the above
