Please solve this problem with step-by-step.

l} The value of Young's modulus (GPa) was determined for cast plams consisting of certain interrnetallic substrates, resulting in the following sample observations: 119.6 1171.4 115.9 112.6 115.2 114.3 11113 a) Calculate f and the deviations from the mean. (1125 points) b) Use the deviations calculated in part {a} to obtain the sample variance and the sample standard deviation. {[1511 points) c) Calculate s2 by using the computational formula for the numerator 311. ((125 points)
