Appropriate control limits for the data, Operation Management

A quality team at Milburn Textiles has been charged with setting up control charts to monitor a key dyeing process that has been improved and now stable.  The ideal temperature for the process is 140 degrees.  Too high a temperature results in excessively dark fabric.  Too low a temperature results in streaking.  Daily temperature readings are taken of the dye vats as shown below.
