1. (based on #18, p. 293) The U.S. Army commissioned a study to asses how deeply a bullet penetrates certaimic body armor. In the standard test, a cylindircal clay model is layered under the armor vest. A projectile is then fired, causing an indentation in the clay, The deepest impression in the clay is measured as an indication of survivability of wearing the armor. Here is data from one testing organization under controlled experimental conditions. Measurements (in mm) were made using a manually controlled digital caliper. 22.4 29.1 31.7 33.5 35.4 37.4 23.6 29.6 31.9 33.5 35.4 37.5 24 29.7 31.9 33.6 35.5 37.5 24.9 29.8 32 33.6 35.7 38 25.5 29.9 32.1 33.8 35.8 38.7 25.6 30 32.4 33.9 36 38.8 25.8 30.4 32.5 34.1 36 39.8 26.1 30.5 32.5 34.2 36 41 26.4 30.7 32.6 34.6 36.1 42 26.7 30.7 32.9 34.6 36.1 42.1 35 36.2 44.6 33.1 33.3 27.4 31 48.3 55 27.6 31 35.2 36.4 28.3 31.4 33.5 35.2 36.6 29 31.6 33.5 35.4 37 x= 33.37, s =5.27 Do the data appear to come from a normally distributed population?…
