(a) Identify the claim and state the null and alternative hypotheses.
Ha: Skill level in a subject is
location
H.: Skill level in a subject is
location
The
V is the claim.
(b) Determine the degrees of freedom, find the critical value, and identify the rejection region.
What are the degrees of freedom?
d.f. =
Find the critical value.
(Round to three decimal places as needed.)
Choose the correct rejection region below.
O A. <x%
O B. 7sx3
OC. z x3
O D. > x3
(c) Calculate the test statistic. If convenient, use technology.
(Round to three decimal places as needed.)
(d) 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 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.
OC. Fail to reject the null hypothesis. There is enough evidence to reject the claim that skill level in a subject is independent of location.
O D. Reject the null hypothesis. There is not enough evidence to reject the claim that skill level in a subject is independent of location.
