Control Charts Control charts‚ also known as Shewhart charts are tools used to determine if a manufacturing or business process is in a state of statistical control. The control chart was invented by Walter A. Shewhart‚ (also known as the father of statistical quality control) while working for Bell Labs in the 1920s. The company’s engineers were seeking to improve the reliability of their telephony transmission systems. The engineers had realized the importance of reducing variation in a manufacturing

1: The mean time to clean a motel room is 15.0 min and the standard deviation is 1.6 min and the data are normally distributed. a. What percentage of the rooms will take less than 12.0 min to complete? Answer: 0.0301% Reasoning/Work: from my understanding I subtracted 1.8 from 1.88 which is my answer = .08 then I found the answer on the table b.
