Exercise 3J1: X and MR-Chart Problem (5 Points). Muncie Trucking Company (MTC) believes that a trucker driving the southern leg of its 1-69 route may be stopping at the casino in Anderson. Before confronting the driver, management has asked you to construct X and MR-Bar Charts to examine the trucker's variability in their delivery times. Normal delivery time on the 1-69 route is 6.5 hours. Based on the travel times given, does it appear that the trucker's delivery times are normal (i.e., the process is In Control)? Or does it appear there may be another cause? Truncate all calculations at 2 decimal places. Assume the moving range is to be calculated using 3 consecutive time periods. To receive full credit you must show proper calculations, neatly draw control limits, specifically state whether each chart for the process is in control and why, and LABEL THE CHARTS AS TAUGHT IN CLASS!
