Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations. 116.2 115.5 114.7 115.2 115.6 (a) Calculate X (in GPa). GPa Calculate the deviations from the mean. X 116.2 115.5 114.7 115.2 115.6 deviation (b) Use the deviations calculated in part (a) to obtain the sample variance (in GPa²). s² = GP₂2 Use the deviations calculated in part (a) to obtain the sample standard deviation (in GPa). (Round your answer to three decimal places.) S= GPa (c) Calculate s² (in GPa2) by using the computational formula for the numerator Sxx GPa2
