Is there a difference in the car brand's countries for Midwesterners and people from the west coast? Of the 165 randomly selected Midwesterners surveyed 60 had an American car, 85 had a car from Asia, and 20 had a cars from another country. Of the 170 randomly selected people from the west coast who were surveyed, 47 had an American car, 83 had a car from Asia, and 40 had a car from outside of the US and Asia. Conduct the appropriate hypothesis test using an α = 0.01 level of significance. What is the correct statistical test to use? Independence Goodness-of-Fit Paired t-test Homogeneity What are the null and alternative hypotheses? H 0 : Address and car brand's countries are dependent. The distribution of car brand's countries is not the same for Midwesterners and people from the west coast. Address and car brand's countries are independent. The distribution of car brand's countries is the same for Midwesterners and people from the west coast. H 1 : Address and car brand's countries are independent. The distribution of car brand's countries is not the same for Midwesterners and people from the west coast. Address and car brand's countries are dependent. The distribution of car brand's countries is the same for Midwesterners and people from the west coast. The test-statistic for this data = (Please show your answer to three decimal places.) The p-value for this sample = (Please show your answer to four decimal places.) The p-value is α Based on this, we should accept the null reject the null fail to reject the null Thus, the final conclusion is... There is sufficient evidence to conclude that address and car brand's countries are dependent. There is insufficient evidence to conclude that the distribution of car brand's countries is not the same for Midwesterners and people from the west coast. There is insufficient evidence to conclude that address and car brand's countries are independent. There is sufficient evidence to conclude that the distribution of car brand's countries is the same for Midwesterners and people from the west coast. There is sufficient evidence to conclude that the distribution of car brand's countries is not the same for Midwesterners and people from the west coast.
