Question
![During the first 13 weeks of the television season, the Saturday evening 8:00 p.m. to 9:00 p.m. audience proportions were recorded as ABC 31%, CBS 26%, NBC 27%, and independents 16%. A sample of 300 homes two weeks after a Saturday night schedule revision yielded the following viewing audience data: ABC 97 homes, CBS 68 homes, NBC 81 homes, and independents 54 homes.
Test with α = 0.05 to determine whether the viewing audience proportions changed.
State the null and alternative hypotheses.
