Question

Variables: Region, Preferred_Status

Is there an association between the state in which a student lives and the student's preferred status?

H₀: The state in which a student lives and a student's preferred status are not associated.

H_A: The state in which a student lives and a student's preferred status are associated.

Answer 1

Is there an association between the state in which a student lives and the student's preferred status?

H₀: The state in which a student lives and a student's preferred status are not associated.

H_A: The state in which a student lives and a student's preferred status are associated.

a) Here we want to do Chi-sqaure test of independence.

When we want to test that the their is an association between the two variables, we do the chi-sqaure test of independece.

Here we want to find that there an association between the state in which a student lives and the student's preferred status.

So here we have to do Chi-sqaure test of independence.

B) Is the sample size large enough to perform the hypothesis test? Explain.

Yes,

The requirement for the chi-squre test is that value of the cell expecteds should be 5 or more.

Here all cells have value 5 or more.

So sample size is enogh.

C)

We reject Ho if P-value is less than level of significance.

I.eP-value is less than 0.01,0.05,0.10

Here P-value = 0.6617

Here P-value is very large.

We fail to rejcet Ho.

So we may conclude that the data do not provide sufficient evidence to support claim that the there an association between the state in which a student lives and the student's preferred status.
