Hey guys.
We are using the chi squared test to determine if there is a significant difference in the observed data and expected data.

i have worked out the X^2 as 37.015 and i have 41 different categories so the degree of freedom is 40.
I'm just having trouble goin on from here with the hypotheses and rejecting Ho or not.
