[WEIBULL DISTRIBUTION COMPARISON]
Suppose a phone manufacturer has two models, aPhone and bPhone, with both having a Mean time to Failure (MTTF) following a Weibull distribution with scale parameter beta =1 and respective shape parameters alpha 0.5 and 5 respectively. (aPhone alpha=0.5 and bPhone alpha=1)
Which phone model is more favorable when not taking into account factors of cost and availability?
