Presented here are 100 measurements of the velocity of light in air (km/sec) recorded by Albert Michelson, an American physicist, from June 5 to July 2, 1879. The measurements have had 299,000 subtracted from them and then were adjusted for corrections used by Michelson. In this form, the true constant value for the velocity of light in air becomes 734.5 km/sec. Do Michelson€™s measurements support the true value that he was trying to measure? Use a 0.01 level of significance.
