A survey asked Democrats, Republicans, and Independent voters what the most important message is to send to Congress. One of the most popular responses for all three groups was to “focus on the economy.” The number of respondents, the messages they want sent, and their party affiliations are shown in the following table:
a. Using α = 0.05, perform a chisquare test to determine if the proportion of voters who responded “ focus on the economy” differs among the three groups of voters.
b. Determine the pvalue using Excel and interpret its meaning.
c. Confirm your results with PHStat.
d. How does party affiliation appear to affect the likelihood that a voter will choose the “focus on the economy” message to send to Congress?
