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:
n0 = 22 ; n1 = 23 ; n2 = 29 ; n3 = 31 ; n4 = 26 ; n5 = 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
