Use the sample data below to test the hypotheses Ho: P1 = P2 = P3 H₂: not all population proportions are equal where p, is the population proportion of Yes responses for population i. Response Yes No Populations 1 2 3 145 140 111 95 140 119 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. 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 cannot conclude that not all population proportions are equal.
