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).

(a) Identify the claim and state the null and alternative hypotheses.
Ho: Skill level in a subject is
location.
Ha: Skill level in a subject is
location.
The
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.
C. Reject the null hypothesis. There is enough evidence to reject the claim
that skill level in a subject is independent of location.
O D. Fail to reject the null hypothesis. There is enough evidence to reject the
claim that skill level in a subject is independent of location.
