The human resources department at a large company regularly conducts an
employee satisfaction survey. One item on the survey presents employees
with the statement, "I am happy overall at work." Based on historical data,
here is the distribution of responses to this item:
Response Strongly agree Agree Disagree Strongly disagree
Historical distribution 70% 15% 5% 10%
The human resources department wants to test if the most recent
responses fit the historical distribution. Here is a sample of 150 of the
most recent responses to the statement along with a chi-square goodness-
of-fit test.
