The yield strength of a sample of 50 tensile specimens from an alloy steel is ž = 130.1 ksi. The Range of yield strength values is from 115 to 145 ksi. (a)Estimate the standard deviation which measures the variability in the strength (b)Assuming a Normal distribution applies, estimate the value of yield strength which 99 percent of the yield strength will exceed.
