a. At the 0.05 level of significance, is there evidence of a difference in the mean cost of importing across the four global regions? Determine the hypotheses. Choose the correct answer below. OA. Ho H₂H4 H₁: Not all μ, are equal (where j = 1,2.....4) OC. Ho H₁ H₂H4 H₁ H₂H₂H4 Find the test statistic. The test statistic is = (Round to two decimal places as needed.) Determine the p-value. p-value = (Round to three decimal places as needed.) b. The critical value is (Round to three decimal places as needed.) The degrees of freedom of the numerator (Source: Among Groups) is The degrees of freedom of the denominator (Source: Within Groups) is B. Ho H₁ H₂ = μ10 H₁: Not all μ are equal (where j = 1,2,...,10) = 10 H10 OD. Ho: H₁ H₂= H₁: H₁ H₂
