A company that processes health claims maintains three centers. Software was installed so they could monitor non-business internet usage by their employees. Initially, six employees were randomly selected from each of three service centers and the number of hours of non-business internet usage recorded.

Use the \(H\) test at the 0.05 level of significance to test the null hypothesis that the 3 samples come from identical populations.
