Public Health and Nutrition The head of the Ontario Medical Association recently suggested that companies should stop requiring a sick note from a doctor when an employee is ill and stays home.43 The practice of requiring a note is often demeaning and discouraging, and sick employees should stay home. A sample of Canadian companies was obtained, and each was classified as requiring a sick note (R) or not requiring any justification (N). The sequence of observations is given in the following table.

Is there any evidence to suggest that the order of observations is not random? Use the runs test with the normal approximation and a = 0.05. Find the p value associated with this test.
