in 2021 Mulungushi University conducted a survey of its first year postgraduate students to collect demographic and health information for future planning purposes as well as to assess students' satisfaction with their postgraduate experiences. The survey revealed that a substantial proportion of students were not engaging in regular exercise whilst on campus, many felt their nutrition was poor (food prepared badly at the dining) and a substantial number were smoking (individual risk behaviors). In response to a question on regular exercise, 60% of all postgraduates reported getting no regular exercise, 25% reported exercising sporadically and 15% reported exercising regularly. In 2022, the University launched a health promotion campaign on campus in an attempt to increase health behaviors among postgraduate students. The program included modules on exercise, nutrition and smoking cessation. To evaluate the impact of the program, the MU again surveyed postgraduates and asked the same questions. The survey was completed by 470 students and the following data were collected on the exercise question: No Regular Exercises = 225; Sporadic Exercises 125; Regular Exercises 90; and Total Survey students 470. 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 significance given that the critical value for this chi-square test is 5.99. In answering this question, show all your working please.
