Question
Use the sample data below to test the hypotheses Ho: P₁ = P₂ = P3 Ha: not all population proportions are equal where p; is the population proportion of Yes responses for population i. Response Yes No Populations 145 2 3 155 96 95 155 104 Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value Using a 0.05 level of significance, state your conclusion. O Do not reject Ho. We cannot conclude that not all population proportions are equal. O Do not reject Ho. We conclude that not all population proportions are equal. O Reject Ho. We conclude that not all population proportions are equal. Reject Ho. We cannot conclude that not all population proportions are equal.
