PROBLEM 1: According to the Commission on Higher Education, College professors work for an average of 43 hours per week during a semester. A dean of Universify X surveys 25 randomly selected professors and found out that they work for an average of 45 hours a week with a standard deviation of 7 hours. Test if the mean number of professors' work hours worked recorded by the dean of University X differs from the recorded national average. Use a = 0.01 Formulate the hypothesis 1. Ho: 2. HA: 3. Given: 5. Solve for t: S = n = a = 4. Test statistics: 7. d. f. = 8. Solve the critical value (te) 6. t = 10. 9. Te
