Question
Transcribed Image Text:An article gives arguments for why fracture toughness in concrete specimens should have a Weibull distribution and presents several histograms of data that appear well fit by superimposed Weibull curves. Consider the following sample of size n = 18 observations on
(i - 0.5)
toughness for high-strength concrete (consistent with one of the histograms); values of p; =
are also given.

Comment on the plot.
The plot shows no relationship. This indicates a Weibull distribution might not be a good fit to the population distribution of fracture toughness in concrete specimens.
● The plot shows a strong curved relationship throughout. This indicates a Weibull distribution might not be a good fit to the population distribution of fracture toughness in concrete specimens.
