Question

The density of the earth relative to the density of water is known to be 5.517 g/cm3. Henry Cavendish, an English chemist and physicist (1731–1810), was the first scientist to accurately measure the density of the earth. Following are 29 measurements taken by Cavendish in 1798 using a torsion balance.
a. What evidence do you have that the assumption of normality is reasonable? Explain.
b. Is the mean of Cavendish’s data significantly less than today’s recognized standard? Use a 0.05 level of significance.
