Chi-Squared Test of Association/Independance

A survey was conducted of 200 people and their responses were categorized by party affiliation and opinion on gun control. The results are shown in this table.

A) Fill in the table below with the expected counts

B) Based on this sample, does a person\'s opinion on gun control depend on party affiliation, at the .05 level of significance?

Observed	Favor	Oppose	Unsure	Total
Democrat	44	48	18	110
Republican	32	48	10	90
Total	76	96	28	200

(A)

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

(B) Null hypothesis: a person\'s opinion on gun control do not depend on party affiliation

Alternative hypothesis: a person\'s opinion on gun control depend on party affiliation

The test statistic is

chisquare=2.20

the degree of freedom =2

the p-value=0.3325 (from chisquare table)

Since the p-value is larger than 0.05, we do not reject the null hypothesis.

So we can not conclude that a person\'s opinion on gun control depend on party affiliation
