Question

Based on the sample data, what will be the upper control limit of a 3-sigma chart? a. 3 times the standard deviation b. 2 times the standard deviation c. 1 times the standard deviation d. 4 times the standard deviation

Answer 1

Explanation:

The upper control limit (UCL) of a 3-sigma control chart is typically calculated as:

UCL = Mean + (3 * Standard Deviation)

So, based on the sample data, the UCL would be:

a. 3 times the standard deviation
