(a) Identify the claim and state the null and alternative hypotheses.
Ho: Skill level in a subject is
Ha: Skill level in a subject is
The
is the claim.
▼ location.
▼ location.
(b) Calculate the test statistic. If convenient, use technology.
x²=0
(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. Fail to reject the null hypothesis. There is enough evidence to reject the claim that skill level in a subject is
independent of location.
OC. 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.
B. Reject the null hypothesis. There is not enough evidence to reject the claim that skill level in a subject is
independent of location.
D. Reject the null hypothesis. There is enough evidence to reject the claim that skill level in a subject is independent
of location.
