In а mаnufаcturing prоcess, the time required tо prоduce one item is approximately normally distributed with a standard deviation 5 minutes. To estimate the mean time used to produce one item, a random sample is taken and the sample mean is used to estimate the mean time. If a random sample of size 50 is taken and the sample mean is 55 minutes, what is the 95% confidence interval for the mean time?
