2. The following data on crack depth ( m) was read from a graph in the article "Effects of Electropolishing on Corrosion and Stress Corrosion Cracking of Alloy 182 in High Temperature Water" (Corrosion Sci. 2017: 1–10) 3-3 3-4 4.3 4-5 4.6 4.7 4.8 8.0 3.6 3-7 3.8 3.9 4.1 5.2 5-3 5-5 5,6 5-9 8.0 1.5 2.9 3.1 6.1 6.9 7.2 7-5 8.1 8.2 8.5 9.2 9-5 9.9 10.0 10.5 10.5 10.7 10.9 10.9 11.2 11.3 11.3 11.8 12.0 12.7 14.4 15.7 17.3 18.4 19.9 20.0 21.7 21.8 22.4 26.4 33-7 33-8 34.0 37.8 42.2 46.0 48.6 50.2 51.4 52.4 66.5 76.1 81.1 (a) Construct a stem-and-leaf display of the data. (b) What is a typical, or representative, crack depth? (c) Does the display appear to be highly concentrated or spread out? (d) Does the distribution of values appear to be reasonably symmetric? If not, how would you describe the departure from symmetry? (e) Would you describe any observations as being far from the rest of the data (outliers)?
