Hello professor,
I am not getting question number 29 of mixed review of chapter 13?

Hi Annum,
This question is asking you to check the expected values to ensure that they are all at least five. In chapter 13, you learned that for the Chi-square procedures the expected values must be greater than or equal to five. For a two-way contingency table, the expected value is found by performing (row total)*(column total)/ grand total for every cell in the table.
If you do this, you will see that indeed every cell has an expected value that is at least 5.

Hi Annum,
You only need to post your question once. After I read, approve the question, and respond, your question and its answer will appear on the site.
