Problem 4. A survey was conducted using employees of a company about health issues. The results revealed that in response to a question on regular exercise, 65% of employees reported getting no regular exercise, 25% reported exercising sporadically and 10% reported exercising regularly.
The next year, the company launched a health promotion campaign at work in an attempt to increase health behaviors among employees. To evaluate the impact of the exercise program, the company surveyed 80 employees (n = 80) and asked about the amount of exercise they have been doing. Here are the data. Forty employees reported getting no regular exercise, 24 employees reported exercising sporadically and 16 employees reported exercising regularly.

Based on the data, is there a significant shift in the distribution of responses to the exercise question following the implementation of the health promotion campaign? Run a chi-square goodness-of-fit test at a .05 level of significance.
