The plotting
on Weibull paper shows the raw data. And from Table 1.2
upper and lower lines for 90% confidence may be plotted with respect to
the raw data. Then a computer solution must yield a//so that the sloped
line passes through the raw data and is between the confidence lines

V. GOODNESS OF FIT TESTS
The following tests [1.5,1.17,l.18,1.23]
should be mentioned and judgment
should be exercised as to how much information is desired.
