The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to agi
fenix001 [56]

Answer:

Step-by-step explanation:

Given that

\alpha =2.5 ,\beta =220

The weibull distribution with parameters \alpha \ \ and \ \ \beta

where \alpha =0 \ \ , \beta =0

F(x,\alpha ,\beta) \left|\begin{array}{cc}\frac{\alpha }{\beta } x^{\alpha-1e^-(x/\beta)^\alpha  &x\geq 0\\0&x

Then,

F(x,\alpha ,\beta )=\left|\begin{array}{cc}0&x

A) The probability that a specimen's lifetime is at most 250 is

P(X\leq 250)=F(250,2.7,220)\\\\=1-e^-^(250/220)^{2.7}\\\\=1-0.2436\\\\=0.7564

The probability that the specimen's life time is more than 300 is

P(X>300)=1-P(X\leq 300)\\\\=1-F(300;2.7,220)\\\\=1-(1-e^-^{(300/220)^{2.7}

=e^-^{(300/220)^{2.7}

= 0.0992

b)The probability of the specimen's lifetime is between 100 and 250

P(100

c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is

P(X>x)=0.50\\\\1-P(X

x = 192.07
