Question: The value of Young's modulus (Gpa) was determined for cast plates consisting of certain intermetallic substrates. resulting in the following sample observations ("Strength and Modulus of a Molybdenum-Coated Ti-25Al-10Nb-3U-1Mo Intermetallic," J. of Materials Engr. and Performance, 1997: 46-50):

116.4 115.9 114.6 115.2 115.8

1. Calculate \(\bar{x}\) and the deviations from the mean.
2. Use the deviations calculated in part (a) to obtain the sample variance and the sample standard deviation.
3. Calculate \(s^{2}\) by using the computational formula for the numerator \(S_{x x}\)
