Question

A political poll asked potential voters if they felt the economy was going to get worse, stay the same, or get better during the next 12 months. The party affiliations of the respondents were also noted. To determine if Party Affiliation and Response are dependent, what are the appropriate hypotheses?

Question 2 options:

1) There is not enough information to choose the correct set of hypotheses. 2) HO: Party Affiliation and Response are independent of one another.
HA: Party Affiliation and Response display a negative correlation. 3) HO: Party Affiliation and Response are independent of one another.
HA: Party Affiliation and Response are associated with each other. 4) HO: Party Affiliation and Response are associated with each other.
HA: Party Affiliation and Response are independent of one another. 5) HO: Party Affiliation and Response are not related to one another.
HA: Party Affiliation and Response display a positive correlation.

Explanation / Answer

As we are trying to test the dependence of response on party affiliation of voters, so the claim being tested is -

HA : Party Affiliation and Response are associated with each other.

And the assumption made is that they are independent. So -

H0 : Party Affiliation and Response are independent of one another.

-----------------------

So, option (3) is correct.
