Question

Teenagers make up a large percentage of the market for clothing. Below are data on running shoe ownership in four world regions (excluding China). At ? = .01, does this sample show that running shoe ownership depends on world region?

The hypothesis for the given issue is H0: Age Group and World Region are independent.

Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.)

Find the critical value for chi-Square. Refer to the chi-square Appendix E table. (Round your answer to 2 decimal places.)
