Employers particularly want to know which days of the week employees are absent in a five-day work-week. Most employers would like to believe that employees are absent equally during the week. That is, the average number of times an employee is absent is the same on Monday, Tuesday Wednesday, Thursday, or Friday. Suppose a sample of 20 absent days was taken and the days absent were distributed as follows: Monday Tuesday Wednesday Thursday Friday Number of Absences 5 4 2...

A researcher studied a random selection of 200 heart attack victims and recorded the day of the week that their attack occurred. The following table summarizes the results: Day Sunday Monday Tuesday Wednesday...
