-2 points DevoreSta18 1 AE.011 My Notes Corrosion of reinforcing steel is a serious problem in concrete structures located in environments affected by severe weather conditions. For this reason, researchers have been investigating the use of reinforcing bars made of composite material. One study was carried out to develop guidelines for bonding glass-fiber-reinforced plastic rebars to concretet. Consider the following 48 observations or measured bond strength: Exampl e 1.11 11.5 12.1 9.9 9.3 7.8 62 6.6 7.0 13.4 17.1 9.3 5.6 5.7 5.4 5.2 5.1 49 10.7 152 8.5 4.2 4.0 3.9 3.8 3.6 3.4 20.6 25.5 13.8 12.6 13.1 8.9 8.2 10.7 142 7.6 5.2 5.5 5.1 5.0 52 4.8 41 3.8 3.7 3.6 3.6 3.6 Ciass Frequency Relative frequency .1875 .3125 .1042 .1875 .1667 Density 15 094 156 052 0417 004 047 021 The resulting Select.. out much farther than does the left or lower tail-a substantial departure from symmetry 7 appears in the figure below.
