You can also solve the above equation for n: You can use this equation to solve for the number of samples you need for given values of α, β, s and δ. There are three ways to decrease δ based on the equation above: Most of the time, we like using 95% confidence level so we don’t want to change α. We are now sampling from the distribution on the right. We want to make errors as seldom as possible – so we want to minimize how often we make Type 1 errors (that is we want α to be small) and how often we make Type 2 errors (that is we want β to be small).
