It sees all the required data is in the tabel under the problem.

In 1879, A. A. Michelson made 100 determinations of the velocity of light in air using a modification of a method proposed by the French physicist Foucault. He made the measurements in five trials of 20 measurements each. The observations (in kilometers per second) follow. Each value has 299,000 subtracted from it (See LIGHT sheet of the given Excel data file). The currently accepted true velocity of light in a vacuum is 299,792.5 kilometers per second. Stigler (1977, The Annals of Statistics) reported that the \"true\" value for comparison to these measurements is 734.5. Construct the Normality plots for Trial 4 and Trial 5. Construct comparative box plots of these measurements. Does it seem that all five trials are consistent with respect to the variability of the measurements? Are all five trials centered on the same value? How does each group of trials compare to the true value? Could there have been bias in the measuring instrument?
