the contingency table shows how a random sample of college freshmen graded the leaders of three types of institutions. at $alpha = 0.10$, can you conclude that the grades are related to the institution? complete parts (a) through (d). (a) identify the claim and state the null and alternative hypotheses. $h_0$: grades are blank the institution. $h_a$: grades are blank the institution. the blank is the claim.
Answer
# Explanation:
## Step1: Define null and alternative hypotheses
The null hypothesis ($H_0$) is that there is no relationship between the variables. The alternative hypothesis ($H_a$) is that there is a relationship.
$H_0$: Grades are **independent of** the institution.
$H_a$: Grades are **dependent on** the institution.
The claim is usually the alternative hypothesis in tests of independence.
## Step2: Identify the claim
The claim is that grades are dependent on the institution, which is $H_a$.
# Answer:
$H_0$: Grades are independent of the institution.
$H_a$: Grades are dependent on the institution.
The $H_a$ is the claim.
