Exercise 3J2: X and MR-Chart Problem 2 (5

Exercise 3J2: X and MR-Chart Problem 2 (5 Points). Each morning, Cardinal Coffee Shop (CCS) tests the temperature (in degrees Fahrenheit) of the first pot of coffee it brews each day to insure its brewer is working properly. Assume the manager has asked you to construct X and MR-Charts to examine the temperature variability of the coffee brewer. Based on the daily temperatures recorded below, does it appear that brewing process is stable? Truncate all calculations at two decimal places. Assume the moving range is to be calculated using 4 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!
