6.50 How's it going?: The American National Election Studies (ANES) collects data on voter attitudes and intentions as well as demographic information. In this question we will focus on two variables from the ANES dataset (ANES, 2012). • region (levels: Northeast, North Central, South, and West) • whether the respondent feels things in this country are generally going in the right direction or things have pretty seriously gotten off on the wrong track To keep calculations simple we will work with a random sample of 500 respondents from the ANES dataset. The distribution of responses are as folows: Right Direction Wrong Track Total Northeast 29 54 83 North Central 44 77 121 South 62 131 193 West 36 67 103 Total 171 329 500

region (levels: Northeast, North Central, South, and West)
• whether the respondent feels things in this country are generally going in the right direction or things
have pretty seriously gotten off on the wrong track
To keep calculations simple we will work with a random sample of 500 respondents from the ANES dataset.
The distribution of responses are as folows:

There are TW0 parts to this question. One is a Chi-Squared GOF and one is a Chi-Squared Test for
Independence. Think about the differences between the two tests to determine which one to use on which
part.
a) Region: According to the 2010 Census, 18% of US residents live in the Northeast, 22% live in the North
Central region, 37% live in the South, and 23% live in the West. Is this sample representative of the
population distribution of US residents?
