1. State the null hypothesis

2. Select an appropriate alternative hypothesis

3. Choose the appropriate statistical test

4. Select the desired level of significance to be used

5. Compute the calculated value and determine the critical test value

6. Make the decision. Reject the null hypothesis if the calculated value is larger than the critical value, otherwise, do not reject the null.

1. A University conducted a survey of its recent graduates to collect demographic and health information for future planning purposes as well as to assess students' satisfaction with their undergraduate experiences. The survey revealed that a substantial proportion of students were not engaging in regular exercise, many felt their nutrition was poor and a substantial number were smoking. In response to a question on regular exercise, 60% of all graduates reported getting no regular exercise, 25% reported exercising sporadically and 15% reported exercising regularly as undergraduates. The next year the University launched a health promotion campaign on campus in an attempt to increase health behaviors among undergraduates. The program included modules on exercise, nutrition and smoking cessation. To evaluate the impact of the program, the University again surveyed graduates and asked the same questions. The survey was completed by 470 graduates and the following data were collected on the exercise uestion: No Regular Sporadic Regular Total Exercise Exercise Exercise Based on the data, is there evidence of a shift in the distribution of responses to the exercise question following the implementation of the health promotion campaign on campus? Run the test at a 5% level of signicance
