Employers 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. Suppose a random sample of 60 managers were asked on which day of the week they had the highest number of employee absences. The results were distributed as in the Table Below. Determine the Chi Square Test Statistic.Please explain how you derived the answer Mon Tues Wed Thurs Fri Number of Absences 16 8 12 10 14
L. As a general rule of thumb, if the items selected for a sample are not replaced and the sample size is less than 5 percent of the population, the binomial distribution can be used to approximate the hypergeometric distribution, il. If the probability of success does not remain the same from trial to trial when sampling is done without replacement, the hypergeometric distribution should be applied. I. In the hypergeometric distribution the probability of a success is not the same on each trail. Multiple Choice (0.00, and (i) are all false statements. () and () are correct statements but not (0. 00 and (i) are correct statements but not ()
