Question: The Quinnipiac University Poll conducts nationwide surveys as a public
The Quinnipiac University Poll conducts nationwide surveys as a public service and for research. This problem is based on the results of one such poll taken in May 2008. Independent simple random samples of 300 residents each in red (predominantly Republican), blue (predominantly Democratic), and purple (mixed) states were asked how satisfied they were with the way things are going today. The following table summarizes the responses.
At the 10% significance level, do the data provide sufficient evidence to conclude that the satisfaction-level distributions differ among residents of red, blue, and purple states?
