a.Choose the appropriate alternative hypothesis to test whether the TV station's claim can be rejected by the data. At least one of the population proportions differs from its hypothesized value.All population proportions differ from their hypothesized values.
b-1.Calculate the value of the test statistic. (Round intermediate calculations to 4 decimal places and your final answer to 2 decimal places.)
b-2.Approximate the p-value. 0.010 < p-value < 0.025p-value < 0.0050.005 < p-value < 0.0100.025 < p-value < 0.0500.050 < p-value < 0.100
