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.\[ H_0: \text{The proportions are not } p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_1: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_0: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_1: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_0: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_1: \text{The proportions are not } p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_0: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p_{IND} = 0.16. \]\[ H_1: p_{ABC} = 0.31, p_{CBS} = 0.26, p_{NBC} = 0.27, p

Let pi's be the population proportions of ABC, CBS, NBC, and Independents respectively.

Use the expression in the accompanying discussion of sample size to find the size of each sample if you want to estimate the difference between proportions of men and women who own smartphones. Assume that you want 95% confidence that your error is no more than 0.02. A Click the icon to view the discussion of sample size. The sample should include men and women. (Type whole numbers.) Sample size discussion The sample size needed to estimate the difference between two population proportions to within a margin of error E with a confidence level of 1-a can be found by using the following expression: P191 P292 E=Za/2 n1 n2 Replace n, and n2 by n in the preceding formula (assuming that both samples have the same size) and replace each of p,, 9,, P2, and q2 by 0.5 (because their values are not known). Solving for n results in this expression: a/2 n = 2E? Print Done

Read the scenario below. Identify the population and sample. Then determine if the bolded value is a parameter or a statistic. Use the appropriate symbol in your answer. A 1993 survey conducted by the Richmond Times-Dispatch one week before Election Day asked voters which candidate for the state's attorney general they would vote for. 37% of the respondents said they would vote for the Democratic candidate. On Election Day, 41% actually voted for the Democratic candidate. The population is The sample is This is a scenario involving The symbol goes with 37% because 37% is a The symbol v goes with 41% because 41% is a
