Give the control limits for 2 standard deviations around the mean, if the mean is 50 and standard deviation is 2. => 46, 92 or 44, 56 or 46, 54 or 48, 52..

Standard Deviation - of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted by s (sigma)...

Sketch a normal curve whose mean is 85 and standard deviation is 7. => Figure 1 or Figure 2 or Figure 3 or Figure 4..

In this series too deviations may be taken either from the actual mean or from standard mean. The calculations will be simplified if the deviation are taken from assumed mean..
