Question:
Ten bearings made by a certain process have a mean diameter of \(0.5060 \mathrm{~cm}\) and a standard deviation of \(0.0040 \mathrm{~cm}\). Assuming that the data may be looked upon as a random sample from a normal population, construct a 95\% confidence interval for the actual average diameter of bearings made by this process.
