SCENARIO 12-8 A study was conducted to determine whether the use of seat belts in motor vehicles depends on the educational status of the parents.A sample of 792 children treated for injuries sustained from motor vehicle accidents was obtained, and each child was classified according to (1)parents' educational status (College Degree or Non-College Degree)and (2)seat belt usage (worn or not worn)during the accident.The number of children in each category is given in the table below.
-Referring to Scenario 12-8, which test would be used to properly analyze the data in this experiment?
A) test for independence
B) test for differences among more than two proportions
C)Wilcoxon rank sum test for independent populations
D)Kruskal-Wallis rank test

The test for independence is appropriate for analyzing the relationship between two categorical variables (parents' educational status and seat belt usage) and determining whether they are independent or dependent. This test will allow us to determine whether there is a significant association between parents' educational status and seat belt usage among the children treated for injuries sustained from motor vehicle accidents. The appropriate test for analyzing categorical data with two variables (in this case, parents' educational status and seat belt usage) is the test for independence. This test determines whether there is a relationship between the two variables, meaning that one variable is dependent on the other. Therefore, option A is the best choice. Option B is incorrect because it is used for comparing more than two proportions. Options C and D are applicable for comparing continuous data, which is not the case in this scenario.
