An article published in USA Today asserts that many children are abandoning outdoor for indoor activities.

The National Sporting Goods Association annual survey for 2004 (the latest data available) compared activity levels in 1995 versus 2004. A random selection of children (7- to 11-year-olds) indicating their favorite outdoor activity is given in the following table:

Bicycling Swimming Baseball Fishing Touch Football 1995 68 60 29 25 16 2004 47 42 22 18 10 Construct a contingency analysis to determine if the type of preferred outdoor activity is dependent on the year in this survey. Use a significance level of 0.05 and the p-value approach.

The file entitled Retirement contains the total savings and investments indicated. Use a contingency analysis to determine if the amount of total savings and investments is dependent on the age of the worker.
