Sample size when population standard deviation estimated

Reference no: EM1388340

We wish to estimate the mean weight of machine components of a certain type and require a 93% degree of confidence that the sample mean will be in error by no more than 0.004 g. Find the sample size required. A pilot study showed that the population standard deviation is estimated to be 0.09 g.
