The lifetime of a brake can be modeled as a Weibull Distribution with a ƛ of 1 per 50000 miles. The probability that a brake lasts longer than 30000 miles is 0.8. Find the value of parameter a
Homework Answers
Given : P(X>30000) = 0.8
Now we have x= 30000 , 
= 0.00002
On substituting in F(x), we get c= 1.609

The lifetime of bacteria follows the Weibull distribution. The probability that the bacteria lives for more...
The lifetime of bacteria follows the Weibull distribution. The probability that the bacteria lives for more than 10 hours is 0.7 and that it lives more than 20 hours is 0.3. The probability that among 300 bacteria more than 200 live longer than 10 hours can be computed as P(Z>a). What is the value of a?
