State the null and alternative hypotheses. O Ho: H1 = H2 = H3 H3i Hy # Hz # H3 O Ho: Not all the population means are equal. H: H = H2 = H3 O Ho: H1 = H2 = H3 H: Not all the population means are equal. O Ho: H1 * Hz * H3 Ha: H1 = H2 = H3 O Ho: At least two of the population means are equal. H: At least two of the population means are different. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value =
