Need help with the question from the picture

Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations. 116.8 115.7 114.9 115.4 115.9 (a) Calculate )7 (in GPa). GPa Calculate the deviations from the mean. x 116.8 115.7 114.9 115.4 115.9 (b) Use the deviations calculated in part (a) to obtain the sample variance (in GPa2). Use the deviations calculated in part (a) to obtain the sample standard deviation (in GPa). (Round your answer to three decimal places.) (c) Calculate 52 (in GPaZ) by using the computational formula for the numerator S)\". (d) Subtract 100 from each observation to obtain a sample of transformed values. Now calculate the sample variance (in GPaZ) of these transformed values. Compare it to s2 for the original data. 0 The variance in part (d) is greater than the variance in part (b). O 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)
