Control Chart For Quality Control Procedures

Words to Grok

Can you generate a python code for the below, the code construct a control chart for sample means to help monitor the process.

Tan plc in its quality control procedures sets the warning limit at 0.025 and the action limit at the 0.001 probability point. This means, for example, that the upper action line is set so that the probability of the mean exceeding the line is 0.001. The company produce steel ingots with a mean weight of 6kg and known standard deviation of 800 grams. The output is monitored by taking random samples of four ingots at regular intervals during the production process.
