In the Kruskal-wallis test for the following data, what is the conclusion about the test at .05 significance level? Suppose that each sample include at least five observations. In addition, the hypotheses are as follows: H0 : µ1 = µ2 = µ3 H1: At least one of the population mean is different from others. Select one: A. Fail to reject H0: µ1 = µ2 = µ3. B. Reject H1: At least one of the population mean is different from others. C. Reject H0: µ1 = µ2 = µ3. D. Fail to reject H1: At least one of the population mean is different from others.
Please don't hesitate to give a "thumbs up" for the
answer in case the answer has helped you
At least one of the population mean is different from others
So, we have to reject Ho due to enough evidence.
Select one:
A. Fail to reject H0: µ1 = µ2 = µ3. - false.
B. Reject H1: At least one of the population mean is different from others. - false. we reject Ho
C. Reject H0: µ1 = µ2 = µ3.- CORRECT
D. Fail to reject H1: At least one of the population mean is different from others.- false.
