Problem 5: A Quality Manager decided to analyze the time it takes inspections of parts at Final Inspection. The Quality Manger asks the QA Technicians to record their time for inspections (in minutes). At the end of the week, the Quality Manager examines the amount of time each QA Technician spent inspecting parts as they arrived at Final Inspection. The data below (in minutes) is the times for inspections of parts. 15 28 25 48 22 43 49 34 22 33 27 25 22 20 39 (a) Calculate the Range, Standard Deviation, and Variance for the above data. (b) What does this information tell you about the variability of QA Technicians' length of time on final inspection of parts?
