Question

The waiting time, T, for a particular event follows a gamma distribution with mean mu= 8 and standard
deviation siigma= 4 . Find P(T> 10 ) .

please clear hand writing or print if possible

Answer 1

let the parameters of the gamma distribution be and p.

Given that, mean = 8 and standard deviation = 4 i.e. variance=16

and

Now,

where F is the CDF of T following Gamma distribution
