A study report in Journal of Small Business Management (1977) concluded that self-employed individuals experience higher job stress than individuals who are not self employed. In this study job stress was assessed with a 15-item scale designed to measure various aspects of ambiguity and role conflict. Rating for each of the 15 items were made using a scale with 1-5 response options ranging from strong agreement to strong disagreement. The sum of the ratings for the 15 items for each individual surveyed is between 15 and 75, with higher values indicating a higher degree of job stress. Suppose that similar approach, using a 20-item scale with 1-5 response options, was used to measure the job stress of individuals for 15 randomly selected real estate agents, 15 architects, and 15 stock brokers. The stress levels of the three professions are given below: Stress Level in Percent Real Estate Architect Stockbroker 81 43 65 48 63 48 68 60 57 69 52 91 54 54 70 62 77 67 76 68 83 56 57 75 61 61 53 65 80 71 64 50 54 69 37 72 83 73 65 85 84 58 75 58 58 Using a = 0.05, test for any significant difference in job stress among the three professions [Put the data in excel first. Then use Tools, Data Analysis function, one-factor ANOVA. Show all five steps of hypothesis testing].

8 The manager of a big corporation finds out that on average, 40% of sick days are logged on Mondays and Fridays. Is there enough evidence to believe that employees are taking long weekends because Mondays and Fridays constitute 40 percent of the work week?
