# Question: In 1879 A A Michelson measured the velocity of light in

In 1879, A.A. Michelson measured the velocity of light in air using a modification of a method proposed by the French physicist Foucault. Twenty of these measurements are in table 6E.27 (the value reported is in kilometers per second and has 299,000 subtracted from it). Use these data to set up individuals and moving range control charts. Is there some evidence that the measurements of the velocity of light are normally distributed? O the measurements exhibit statistical control? Revise the control limits if necessary.
