Question
The National Institute of Standards and Technology (NIST) offers Standard Reference Materials to aid in the calibration of
measurement instruments and verify the accuracy of measurements. Suppose a medical researcher wants to verify that the
distances he measures with his computed tomography machine are not too large, so he orders a Dimensional Standard for
Medical Computed Tomography from NIST.
This standard consists of 18 plastic balls held in place by a plastic support structure. The certified distance between the balls
numbered 1 and 3 is 20.15 mm, and NIST determines that measurement errors are normally distributed with a standard
deviation of 0.05 mm. Upon receiving the Standard Reference Material, the researcher measured the distance between balls 1
and 3 six times. Take these six measurements to be a simple random sample of all measurements made on this device under
carefully controlled conditions. The researcher then calculated the summary statistics, where u is the mean distance between
balls 1 and 3, as measured by his computed tomography machine.
Test of u = 20.15 vs u > 20.15
