Lord Rayleigh was one of the early pioneers in studying the density of nitrogen. (Read the Science Connection below.) The following are data that he collected. Lord Rayleigh's measurements first appeared in Proceedings of the Royal Society of London (London, vol. 55, 1894). Each piece of data is the mass in grams of nitrogen filling a certain flask under a specified temperature and pressure.

a. Calculate the five-number summary for each set of data.
b. On the same axis, create a box plot for each set of data.
c. Describe any similarities and differences in the shapes of the box plots. Do the box plots support Lord Rayleigh's conjecture?
