2. Suppose you have data for 20000 individuals about the number of times they had to see a doctor in past 3 months. The following frequency distribution table represents the data, where X represents the number of doctor visits. 1 4000 2 3 4 50 15000 800 150 a. What is the average number of visits? What is the median and the mode? What is the standard deviation? Clearly show/explain how you reached your answer. b. Now suppose that a contagious disease breaks out and affects all these individuals which makes all of them to visit a doctor one more time. What would then be the new mean, median and mode of number of visits? What would be the new standard deviation? Can you answer without doing recalculating these statistics?
