To assess the precision of a laboratory scale, we measure a block known to have a mass of 1 gram. we measure the block n times and record the mean x¯ of the measurements. suppose the scale readings are normally distributed with unknown mean µ and standard deviation σ= 0.001 g. how large should n be so that a 95% confidence interval for µ has a margin of error of ± 0.0001
