Question: To access the accuracy of a laboratory scale, a standard weight known to
weigh 10g is weighed repeatedly. The scale readings are normally distributed with standard deviation 0.0002g.
-
The weight is measured five times. The mean result is 10.0023g. Give a 91.64%
confidence interval for the mean of the true weight. - How many measurements needed to get the bound on the error of estimation with 98% confidence is less than 0.0001?
