Question:

In 1789, Henry Cavendish estimated the density of the earth by using a torsion balance. His 29 measurements follow, expressed as a multiple of the density of water.


(a) Calculate the sample mean, sample standard deviation, and median of the Cavendish density data.
(b) Construct a normal probability plot of the data. Comment on the plot. Does there seem to be a €œlow€ outlier in the data?
(c) Would the sample median be a better estimate of the density of the earth than the sample mean?Why?
