In a fabric manufacturing factory, the quality control process using control charts from SPC. In an hour there are a total of 5 samples are taken
each having 5 observations regarding the thickness of fabric in measured in millimeters. In a particular hour, the sample means (X-bar) are noted to
be: 156.46, 199.62, 189.31, 102.22, and112.09 respectively. In the same sample, the corresponding ranges are: 11.97, 12.17, 13.94, 11.86, and

Using information from the above table:
Calculate the standard deviation of the sample means, σ×.
Determine the control limits for the mean chart, using A2 and σ× if z=3.
Determine the control limits for the range chart.
Construct mean (using A2) and range control charts by using information from (ii) and (iii).
Comment on your results.
