To assess the accuracy of a laboratory scale, a standard weight that is known to weigh 1 gram is repeatedly weighed 4 times. The resulting measurements (in grams) are: 0.95, 1.02, 1.01, 0.98. Assume that the weightings by the scale when the true weight is 1 gram are normally distributed with mean µ. Use these data to compute a 95% confidence interval for u. (2 decimal places) lower limit = upper limit =
