\%- canvas.strayer.edu/courses/15779/assignments/824017?module_item_id=1218797 Not Found Scenario: Customers at II Phone Call Center have been complaining that they are waiting too long for service. Ihe managers do some investigating to determine the typical service time for their customers for morning shifts compared to evening shifts - Morning shifts: \( 7,14,15,17,17,19,20,20,20,55 \) - Evening shifts: \( 2,10,11,13,21,21,29,32,33,46 \) A. Calculate the mean, median, and mode for each shift using the data above. Explain your calculations. B. Determine which descriptive statistic (mean, median, or mode) you would utilize to communicate the typical service time explanation, be sure to include which shift (morning or evening) has the quicker turn-around time.
