To assess the accuracy of a lab scale, a standard weight known to weigh 10 grams is weighed repeatedly. The scale readings are normally distributed with unknown mean and the standard deviation of the scale reading is known to be 0.0002 grams. The following procedure could be used to test whether the scale is accurate (i. e., does the reported weight from the scale equal 10 gramsa. The weight is measured 5 times. The mean result is 10.0023 grams. Give a 98% confidence interval for the mean of repeated measurements of the weight. b. How many measurements must be averaged to get a margin of error of ±0.0001 with 98% confidence?
