Question

The following table lists diameter in millimeters for a sample of 10 ball bearings produced by a machining tool. The manufacturer collected this data for quality control purposes. (The eventual objective is to determine whether the machine is creating ball bearings within the desired error tolerances.)

Label	Diameter (mm.)
1	9.948
2	10.085
3	9.938
4	10.006
5	10.07
6	10.074
7	10.077
8	10.289
9	10.204
10	10.296

Calculate the standard deviation of the diameter. Round your answer to 3 decimal places.
