Question

Assume that the population is infinite in each case

Solve the following problems. Assume that the population is
infinite in each case.
5. A molding machine prepares a certain kind of car
spare part with
millimeters. The machine has some variability, so the
standard deviation of the diameters is o = 0.004
millimeters. A sample of 6 spare parts is inspected each
hour for process control purposes and records are kept
of the sample mean diameter. What will be the mean
a target diameter u = 40.265
and standard deviation of the numbers recorded?
