An electric sale gives a reading equal to the true weight plus a random error that isnormally distributed with mean 0 and standard deviationσ=.1 mg. suppose that the results of fivesuccessive weightings of the same object are as follows: 3.142, 3.163, 3.155, 3.150, 3.141.(a) determine a 95 percent confidence interval estimate of the true weight.
(b) determine a 99 percent confidence interval estimate of the true weight.
