Question

Help!!  I am hitting a road block trying to figure the Chi-squared answer for Chapter 23, #29a.  I get an answer of 22.064 for all rural and suburban internet users, but the book gives an answer of 52.5.  I can't use software to figure this out and my hand calculations are not coming up.  Can someone please show the steps to figuring this out for me??  I see the formula is in the answer, but that doesn't show any numbers used to calculate the answer.  HELP!!  And thanks in advance for responding!!

Explanation / Answer

Can you post the entire question? I don't have the book.
