Problem 1. The data for the fracture toughness of steel base plates have been compiled as shown below. (a) Plot the data on a lognormal probability paper, draw a straight line through the plotted data points, and see if a linear trend can be observed. (b) Estimate the median and coefficient of variation of the fracture toughness on the basis of the straight line you drew in part (a).
