Goodness-of-Fit
Q: In 2008, a random sample of 500 incoming freshmen at the same college yielded the following frequency distribution for political views.
Political View Frequency
Liberal 160
Moderate 246
Conservative 94
At the 5% significance level, do the data provide sufficient evidence to conclude that 2008's distribution of political views for incoming freshmen has changed from the 2007 distribution?
