How to calculate sample size using Power and Sample Size for 1 Sample t test using Minitab?
Suppose you are the quality manager at a semiconductor plant. In order to meet state requirements, you must maintain strict control over the PCB thickness. The thickness cannot vary more than 0.4 mm. The process sigma is 0.05. How many samples must be taken to estimate the mean package volume at a confidence level of 99% for power values of 0.9?
