[Questiоn B] Yоu аre mаnаging custоmer service response times at the I.T. helpdesk. You have measured your average customer service telephone call time over the past year (250 business days), and have created the following three graphs. A customer service call time starts when the customer reaches a representative, and ends when the call hangs up; you have day and night time shifts. You have made the following three charts based on your data. MidTerm_QuestionB_Chart_A_wLabel.png MidTerm_QuestionB_Chart_B.png MidTerm_QuestionB_Chart_C.png At the departmental meeting, one of your co-workers says, “We’ve run our averages over the past year, and our average customer service time is 6.7 minutes, well below the 10 minute target we have established. You can see on the histogram that the mean, median, and mode are all well below the 10 minute mark. This means about two-thirds of our data, per the empirical rule, should be within +/- one stdev, or within the interval [3.0, 10.5] minutes. So I think we’re in good shape.” What is your response to this? Write a few sentences about each chart. In your response, tell me what type of chart is depicted in Chart A, Chart B, and Chart C. And tell me what you see on each chart that confirms or contradicts your co-worker’s comments. (You can assume the co-worker has the 6.7 average calculated correctly, and moreover assume that all three graphs correctly depict the same data set. If you need to make any assumptions about the chart, just note those on your answer.)
