The value for
The value for
Generally the Weibull distribution function is mathematically represented as
Generally the probability that a specimen's lifetime is at most 250 is mathematically represented as
Generally the probability that a specimen's lifetime is less than 250
[texP(X < 250 ) =1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]
Generally the probability that a specimen's lifetime is more than 300
[texP(X < 300) =1- [1 - e^{- (\frac{300}{220} )^{2.7}}][/tex]
Generally the probability that a specimen's lifetime is between 100 and 250 is
