In a Friedman Test for Comparing Four Populations, Provided That

question 60

Short Answer

In a Friedman test for comparing four populations, provided that there are eight blocks, the test statistic is calculated as F = 10.98. If the test is conducted at the 5% significance level, the conclusion and p-value will be: $\begin{array}{|l|l|}\hline A&\text { reject the null hypothesis, and }0.01< P-value<0.025\\\hline B&\text { reject the null hypothesis, and } p -value >0.025 \\\hline C&\text { do not reject the null hypothesis, and p-value<0.05}\\\hline D&\text { do not reject the null hypothesis, and p -value >0.05}\\\hline \end{array}$
