A sample of 300 homes two weeks after a Saturday night schedule revision yielded the following viewing audience data: ABC 91 homes, CBS 63 homes, NBC 82 homes, and Independents 64 homes. Test with a = 0.05 to determine whether the viewing audience proportions changed. Find the test statistic and p-value. (Round your test statistic to two decimal places. Use Table 3 of Appendix B.) Test statistic = 6.78 8 p-value is between 0.05 and 0.10 Conclusion: There is no significant change in the viewing audience proportions.
