The contingency table shows how a random sample of college freshmen graded the
leaders of three types of institutions. At = 0.01, can you conclude that the grades
are related to the institution? Complete parts (a) through (d).
Institution
(a) Identify the claim and state the null and alternative hypotheses.
Ho: Grades are independent of the institution.
H₂: Grades are dependent on the institution.
The alternative hypothesis 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. = 6
Find the critical value.
x=16.812
(Round to three decimal places as needed.)
Choose the correct rejection region below.
OA. <
B. >
OC. sto
D. 20
(c) Calculate the test statistic. If convenient, use technology.
7 = ☐
(Round to two decimal places as needed.)
