Question: In 1798 Henry Cavendish obtained 27 measurements of the density
In 1798, Henry Cavendish obtained 27 measurements of the density of Earth, using a torsion balance. The following data represent his estimates, given as a multiple of the density of water. Is it reasonable to conclude that the sample data come from a population that is normally distributed?
