Density of the Earth
In 1789 the English scientist Henry Cavendish measured the density of the Earth by careful work with tension balance. The variable record was the density of the earth as a multiple of water. Here are Cavendish's 29 measurement.
5.50 5.61 4.88 5.07 5.26 5.55 5.36 5.29
5.58 5.65 5.57 5.53 5.62 5.29 5.44 5.34
5.79 5.10 5.27 5.39 5.42 5.47 5.63 5.34
5.46 5.30 5.75 5.68 5.85
I need help find the answers to these questions. Anybody mind refreshing my memory so I can get this done?
Present the measurements graphically in a stemplot. Discuss the shape, center and spread of the distribution. Are there outliers? What is your estimate of the density of the earth on these measurements?

A Make a boxplot to compare the 3 distributions. Report the five number summaries along with your graphs. What are the most important differences among the 3 varities of flower?
B Find the x and s for each variety.
