The cost associated with importing a standardized cargo of goods by sea transport in these countries (in US$ per container) is stored in the accompanying data table. Complete (a) through (d) below. Click on the icon to view the data table. 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. O A. Ho: H1 = H2= . . . = H4 OB. HO: H1 = H2= . . . = H10 H,: Not all u; are equal H: Not all u; are equal (where j = 1,2,...,4) (where j = 1,2,..., 10) O C. Ho: H1 = H2 = . . . = HA OD. HO: H1 = H2 = . . . = H10 H1: Hy # H2 # . . . # H4 Hy: My $ 12 # . . . # H10 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.)
