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.
For the actual weight
i) write a pivot random variable that can be used for finding confidence interval, which
distribution does this pivot have, explain your answer;
ii)find the 90% and 95% confidence intervals, state the intervals using notion of margin
of error.
