12. As part of an initial investigation exploring foreign market entry, 10 countries were selected from each of four global regions. 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. 1 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. OA. Ho: H =H==10 H: Not all j are equal (where j 1,2,..., 10) OC. Ho H = = H4 H H4. OB. Ho H1 H2= =14 OD. Ho H1 H2= H H: Not all ; are equal (where j 1,2,...,4) =10 110 Find the test statistic. The test statistic is = Determine the p-value. p-value= (Round to two decimal places as needed.) (Round to three decimal places as needed.) (Round to three decimal places as needed.) b. The critical value is The degrees of freedom of the numerator (Source: Among Groups) is The degrees of freedom of the denominator (Source: Within Groups) is 1: Costs of importing a standardized cargo of goods ($) Region 1 Region 2 Region 3 Region 4 893 2308 2250 1320 608 1630 1591 1000 559 905 2274 750 667 973 969 3400 411 1390 2840 1325 653 913 1018 1200 444 1485 1569 1313 715 2926 1023 1023 745 1244 875 1044 606 2159 2867 1635
