Expensive parts are produced in an industrial process. They need to be broken in order to be tested, so a sample of 6 parts is chosen, measuring the % increase in length of the part before breaking. The sample mean is 4.31% and the sample standard deviation is 0.026%. What is the population mean and its confidence interval for 95% confidence? OH = 4.31 ± 0.0273% H= 4.31 2.570% u= 4.31 0.1499% OH = 4.31 + 0.0299%
