2.14 An engineer uses a thermocouple to monitor the tem- perature of a stable reaction. The ordered values of 50 observations (Courtesy of Scott Sanders), in tenths of C, are 1.11 1.21 1.21 1.21 1.23 1.24 1.25 1.25 1.27 1.27 1.28 1.29 1.31 1.31 1.31 1.32 1.34 1.34 1.35 1.36 1.36 1.36 1.36 1.36 1.36 1.36 1.37 1.39 1.40 1.41 1.42 1.42 1.42 1.42 1.43 1.43 1.43 1.44 1.44 1.44 1.47 1.48 1.48 1.50 1.50 1.56 1.56 1.60 1.60 1.68 Group these figures into a distribution having the classes 1.10-1.19, 1.20-1.29, 1.30-1.39,..., and 1.60-1.69, and plot a histogram using [1.10, 1.20), . . .,
