sample size 的计算
The volume for the packaging of ice-cream cannot vary more than 3 oz for a 64 oz container.
The packaging machines have a process variation of 1 oz.
What is the sample size required to estimate the mean package volume at a confidence level of 99% for power values of 0.7, 0.8 and 0.9?
