Why did we use the Chi square test instead of Fisher’s exact test in the previous exercise?

A. It actually does not matter, since they give the exact same p-value.

B. Fisher’s exact and the Chi squareare different names for the same test.

C. Because the sum of the rows and columns of the two by two table ere not fixed so the hypergeometric distribution is not an appropriate assumption for the null hypothesis. For this reason, Fisher’s exact test is rarely applicable with observational data.

D. Because the Chi square test runs faster.
