Question : A computer system has 6 I/O channels and the system personnel are reasonably certain that the load on channels is balanced. If X is random variable denoting the index of the channel to which a given I/O operations is directed , that its pmf is assumed to be uniformly distributed. Out of N=150 I/O operation onserved, the number of operations directed to various channels were:(adsbygoogle = window.adsbygoogle || []).push({});

n_{0}= 22 ; n_{1}= 23 ; n_{2}= 29 ; n_{3}= 31 ; n_{4}= 26 ; n_{5}= 19

Test the hypothesis that the load on channels is balanced at 5 percent level of significance.

Solution

I have used the [tex]\chi[/tex]^{2}= (O-E)^{2}/ E

where O - obsevred and E is expected

Is this correct or should i be using some other method
