I have been constantly bothered by my younger brother for seemingly trivial matters. A couple of years ago, he was about to send my niece to college, and he was interested in the political views of the freshmen at the college.
Anyway, this was what he found. In 2007, 27.7% of incoming freshmen characterized their political views as liberal, 51.9% as moderate, and 20.4% as conservative.
Political View Frequency
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?
The solution provides step by step method for the calculation of chi square test of goodness of fit. Formula for the calculation and Interpretations of the results are also included.
