A television CEO believes viewership of the evening news does not depend on age. She collects a random sample of 2000 television viewers across four different age groups and asks whether or not they watch the evening news. The results are as follows:

Watch | 18 years old 19 to 35 36 to 54 55 years old

Evening News | or less years old years old or more

___________________________________________________________

Yes | 74 96 112 146

No | 426 404 388 354

Test to see whether watching the evening news and age grouping are independent at the 0.05 level using the Chi-Square test. Conduct this test by hand and using the Chi-Square table instead of using Excel.
