Subject Is achieving a basic skill level related to the location of the school? The results of a random sample of students by the location of school and the number of students achieving basic skill levels in three subjects is shown in the contingency table. At a = 0.01, test the hypothesis that the variables are independent. Complete parts (a) through (d). Location Reading Math Science Urban 48 41 39 Suburban 70 63 64 (a) Identify the claim and state the null and alternative hypotheses. Ho: Skill level in a subject is V location. Ha: Skill level in a subject is V location. The V is the claim. (b) Calculate the test statistic. If convenient, use technology. (Round to three decimal places as needed.) (c) Decide to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim. Choose the correct conclusion below. O A. Reject the null hypothesis. There is not enough evidence to reject the claim that skill level in a subject is independent of location. O B. Fail to reject the null hypothesis. There is not enough evidence to reject the claim that skill level in a subject is independent of location. O C. Reject the null hypothesis. There is enough evidence to reject the claim that skill level in a subject is independent of location. D. Fail to reject the null hypothesis.
