BUSI 2301 Lecture Notes - Lecture 1: Standard Deviation, Sampling Distribution, 5,6,7,8
Document Summary
The frequency and quantity of inspection relates primarily to the cost of inspection. The variability of a process is equivalent to the distribution of samples of any size taken from the process. The sampling distribution can be assumed to be approximately normal even when the underlying process distribution is not normally distributed. Approximately 99. 7% of sample means will fall within two standard deviations of the process mean. The purpose of control charts is to: estimate the proportion of output that is acceptable weed out defective items determine if the output is within specifications/specifications. Distinguish between random variation and assignable variation in the process all of these. Which of the following is not a step in the quality control planning process? define the quality characteristic to be controlled determine a quality control point in the process. Eliminate all defects found plan how inspection is to be done all of the choices are steps.
