Question

You have collected data on voters and their recent voting habits. You sample 174 Republicans, 167 Democrats, and 113 Independents (which you have determined to be a reasonable representation of the party-affiliation of voters in your region of interest). The resulting contingency table for your results is provided:

Party Affiliation	Voted
	Yes	No
Republican	69	105
Democrat	78	89
Independent	66	47

Construct the conditional distribution of the voting habits by party affiliation:

Party Affiliation	Voted
	Yes	No
Republican
Democrat
Independent

For comparison purposes, calculate the relative frequency marginal distribution for voting habits:

Voted
Yes	No

Though you do not need to answer it here, what is the association between voting habits and party affiliation?

Answer 1

dividing each value by row total:

conditional distribution of the voting habits by party affiliation :

	Yes	No
Republican	0.3966	0.6034
Democrat	0.4671	0.5329
Independent	0.5841	0.4159

relative frequency marginal distribution for voting habits :

	Yes	No
total	0.4692	0.5308

there appear to be an association between voting habits and party affiliation
