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. OA. Ho H = = =10 H: Not all are equal (where j=1,2,..., 10) C. Ho = ... = 44 #44 B. Ho H =H2= = . . = =4 H: Not all j are equal (where j=1,2,...,4) D. Ho H =2 =10 H: 10 Costs of importing a standardized cargo of goods Find the test statistic. The test statistic is = Determine the p-value. p-value = (Round to two decimal places as needed.)

Advertisement A greatly undersells the pen. Advertisement B slightly undersells the pen. Advertisement C slightly oversells the pen. Advertisement D greatly oversells the pen. Advertisement E correctly states the pen. A sample of 30 adult respondents is randomly assigned to the five advertisements. After reading the advertisement, all respondents unknowingly receive the same pen to evaluate and are then asked to rate the pen from 1 to 7 (lowest to highest) on three characteristics.
