. Determine the mean and median for each shift and compare these with the desired level of 8
micrometers. Which shifts average was closer to the target?

2. If you needed to use one of these parts in your own computer on which shift would you prefer
the part to have been manufactured?
Why?

In order to describe the variability of a set of data, a simple measure is to compute the Range. I
statistical jargon, the Range is the gap between the largest and smallest value in the data set.
Calculate the range for each shift.
