You plan to estimate the mean weight of machine components of a certain type and you require a 95% level of confidence that the sample mean will be within the population mean by 0.008 g. Find the minimum sample size required. A pilot study showed that the population standard deviation is estimated to be 0.06 g.

A1/27 = A2/39 =>

A2 = A1*39/27

A2 = 711×39/27

A2 = 1027 m^2
