In a certain type of metal test specimen, the normal stress on a specimen is known to be functionally related to the shear resistance. The following is a set of coded experimental data on the two variables: Normal Stress, æ Shear Resistance, y 26.5 27.3 26.8 25.4 28.9 24.2 23.6 27.7 23.9 27.1 23.6 25.9 24.7 26.3 22.5 21.7 28.1 26.9
