During the first 13 weeks of the television season, the Saturday evening 8 p.m. to 9 p.m. audience proportions were recorded as ABC 30%, CBS 27%, NBC 26%, and independents 17%. A sample of 300 homes two weeks after a Saturday night schedule revision yielded the following viewing audience data: ABC 96 homes, CBS 69 homes, NBC 90 homes, and independents 45 homes. Test with a = 0.05 to determine whether the viewing audience proportions changed. State the null and alternative hypotheses. O Ho: The proportions are not PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17. Ha: PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17 Ho: PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17 Ha: The proportions are not PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17. O Ho: PABC # 0.30, PCBS * 0.27, PNBC * 0.26, PIND * 0.17 Ha: PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17 O Ho: PABC = 0.30, PCBS = 0.27, PNBC = 0.26, PIND = 0.17 Ha: PABC * 0.30, PCBS * 0.27, PNBC * 0.26, PIND * 0.17 Find the value of the test statistic. (Round your answer to three decimal places.) X Find the p-value. (Round your answer to four decimal places.) p-value = X State your conclusion. O Reject Ho. There has not been a significant change in the viewing audience proportions. Do not reject Ho. There has not been a significant change in the viewing audience proportions. Do not reject Ho.
