- The value of Young’s 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-3U-1Mo Intermetallic,” J. of Materials Engr.and Performance, 1997: 46–50):116.4 115.9 114.6 115.2 115.8a. Calculate x 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 forthe numerator Sxx.d. Subtract 100 from each observation to obtain a sampleof transformed values. Now calculate the samplevariance of these transformed values, and compare itto s2 for the original data.State the t critical value that would be used for a 99% interval based on a sample size of 37.A local restaurant claims that it gets 45 percent of its customers from Monday through Thursday, 20 percent on Friday, 20 percent on Saturday, and 15 percent on Sunday.
