Which of the following statements about the Ground Engaging Tools (teeth) in the EXB8 data in Figure 5of the Weibull case studyis correct? Select one.
a There are insufficient data points to have confidence in parameters produced from this Weibull plot
b A single best fit line should alway be used.
c A component such as a tooth can only ever have one failure mode; there are two lines because this failure mode has two possible mechanisms
d Each type of failure mode can be modelled as a separate Weibull model fit since a tooth can fail in either of the failure modes
