This one is irritating me:

From the years 2001 to 2004, the following data is compiled for political contributions in a particular party:

Made a contribution?

Year Yes No

2001 469 218

2002 582 371

2003 731 589

2004 646 488

Using a 5% level of significance, test the null hypothesis that the percentage of contributors is the same across the stated years.

Ughh!!! Where do I begin? The video lesson on this stuff gives simple, easy to understand examples and then blows you away on the work! Somebody please help.
