Chapter 1, Problem 45(choose chapter or problem)
The value of Youngs modulus (GPa) was determined forcast plates consisting of certain intermetallic substrates,resulting in the following sample observations (Strengthand Modulus of a Molybdenum-Coated Ti-25Al-10Nb-3U1MoIntermetallic, J. of Materials Engr. and Performance,1997: 4650):116.4 115.9 114.6 115.2 115.8a. Calculate and the deviations from the mean.b. Use the deviations calculated in part (a) to obtain thesample variance and the sample standard deviation.c. Calculate s2 by using the computational formula for thenumerator Sxx.d. Subtract 100 from each observation to obtain a sample oftransformed values. Now calculate the sample varianceof these transformed values, and compare it to s2 for theoriginal data.
