To assess the accuracy of a laboratory scale, a standard weight that is known to weigh 1 gram is repeatedly weighed a total on n times and the mean of x of the weighing is completed. Suppose the scale readings are j BJ or ally distributed with unknown mean u And the standard deviarion a= 0.01g. How large should n be so that a 95 % confidence interval for u has a margin of error of error of +|- 0.001?
