Question: A scale gives a reading equal to the true weights plus a random error that is normally distributed with mean 0 and standard deviation \(0.1\). Suppose the results of 4 successive weightings of the same object are as follows:
3.142 3.163 3.155 3.150
(a) Determine a 95% confidence interval
(b) Determine 99% confidence interval
(c) How large should the sample be if the population mean is to be estimated with 95% confidence within 0.01?
