1. ## Help:Chi-Square Test of Independence

Guys i need help on this, please show me how you complete the table. the file has been attached. Thank you

2. I haven't done one of these in years.
But the idea is if they are independent P(AB)=P(A)P(B).
So you obtain the marginal empircal probabilities and see how far we
deviate from that via a goodness of fit test.
I'll do an online search for this.

Yea it's here... http://en.wikipedia.org/wiki/Pearson's_chi-square_test
Look at ...Test of independence
The EXPECTED value in the first cell is ${(54)(66)\over 183}$
Do that for all your cells and obtain the approximate chi-square test.
The dfs is (3-1)(3-1)=4

Your sense of urgency (evidenced by several bumps) and explicit deadline suggests that this question is part of an assignment that might count towards your final grade. MHF policy is to not knowingly help with such questions.
