Chi-squared test of homogeneityD:The polling organization polls people on a regular basis to view their changing confidence in the economy. The organization creates a numerical index from 0 to 100 of confidence in the economy from answers to a survey. Based on a random sample of people who were polled both in 2011 & again in 2012, the organization will assess if confidence in the economy changed from 2011-2012 on average.1.
