16. The article cited in Example 1.2 also gave the accompanying strength observations for cylinders:

6.1 5.8 7.8 7.1 7.2 9.2 6.6 8.3 7.0 8.3 7.8 8.1 7.4 8.5 8.9 9.8 9.7 14.1 12.6 11.2

a. Construct a comparative stem-and-leaf display (see the previous exercise) of the beam and cylinder data, and then answer the questions in parts (b)–

(d) of Exercise 10 for the observations on cylinders.

b. In what ways are the two sides of the display similar?

Are there any obvious differences between the beam observations and the cylinder observations?

c. Construct a dotplot of the cylinder data.
