Will rate!! 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...

pls help, i don't understand what i did wrong Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations: 116.4 115.6 114.6 115.1 115.5 (a) Calculate X. 115.4 GPa Calculate the deviations from the mean.
