Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations. 116.6 115.5 114.9 115.4 115.7
(c) Calculate s2 (in GPa?) by using the computational formula for the numerator Sxx GPa 2 (d) Subtract 100 from each observation to obtain a sample of transformed values. Now calculate the sample variance (in GPa?) of these transformed values. GPa2 Compare it to s2 for the original data. The variance in part (d) is greater than the variance in part (b). The variance in part (d) is equal to the variance in part (b). O The variance in part (d) is smaller than the variance in part (b).
