Shewhart control chart sets the Upper Control Limit (UCL) and Lower Control Limit (LCL) at the 3 times of standard deviation distance from the mean, ie.,UCLsp + 3o, and LCL--3a. Draw a normal distribution curve to demonstrate the type I error allocated in two tails and evaluate the value of under such control limits setting. [4 points UCL- [Hint: The Z-value or Z-score for UCL can be calculated as-cog-3, which corresponds to Za/2]Explanation / Answer
