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. 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 A. H_0: mu_1 = mu_2 = ... = mu_4 H_1: Not all mu_1 are equal (where j = 1, 2, ..., 4) C. H_0: mu_1 = mu_2 = ... = m_4 H_1: mu_1 notequalto mu_2 notequalto ... notequalto mu_4 Find the test statistic. F_STAT = (Round to two decimal places as needed.)
