Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations: 116.7 115.8 1149 115.3 115.9 (a) Calculate x. CEnter your answer to two decimal places.) Calculate the deviations from the mean. (Enter your answers to two dedimal places.) deviation (b) Use the deviations calculated in part (a) to obtain the sample variance and the sample standard deviation. (Round your answers to three decimal places) 116.7 115. 134.9 115.3 115.9 GPa GPa (c) Subtract 50 from each observation to obtain a sample of trandformed values Now calculate the sample mean and sample variance of these transformed values. (Round your answer to three decimal places.) GPal Compare the transformed x and s? to the orlginal data. O The transformed mean and varlance are both the same as the original O The transformed mean is less than the original and the transformed variance is less than original variance. O The transformed mean is less than the original but the trarsformed varlance is the same orlginal varlance O The transformed mean is the same as the original but the transforned varlance is less than the original varlance The transformed mean is less than the original and the transformed variance is greater than original varlance
