mean is 56,” I might think about the sample, while you might think about the population. To make a business decision, we all need to know something about the population, not the sample. Without additional information, the point estimate of 56 is a useless number. The population mean μ ...
Sample size for population mean For a normal distributed population, specifying a 10% estimation error of the population meanμμ(i.e.,μ±0.1μμ±0.1μ) with a 95% confidence level, the sample size can be calculated as: n=(zα/2STO)2=(z0.05/2σ0.1μ)2=384CV2n=(zα/2STO)2=(...
