To assess the accuracy of a metallurgical laboratory scale, a standard weight that is
known to weigh 1 is repeatedly weighed four times. the resulting
measurements (in grams) are: 0.95, 1.02, 1.01, and 0.98. assume the weightings by
the scale when the true weight is 1 are normall distributed with mean .
(i) use these data to construct a 95% confidence interval for �
