The percentage of impurities per batch in a chemical product is a random variable X with density function
12x2(1−x), 0≤x≤1 f(x) =
0, elsewhere A batch with more than 40% impurities cannot be sold.
(a) What is the distribution of X?
given that
(1)
a)
we have to find the distribution of X
Now let Y is type 1 beta distribution with parameters and is given by
let then
(2)
since (1) and (2) have same pdf
Hence X is type 1 beta distribution with parameters with
