# Values of Alpha and Beta

The percentage 'y' of impurities per batch in a certain chemical product is a beta random variable with probability density

f(y)={90y^8(1-y) if 0<=y<=1

0 elsewhere

*90 is above 0 in enclosure

What are the values of alpha and beta?

#### Solution Preview

Because, Beta random variable has the distribution as,

<br>

<br>f(x) = x^(a - 1) (1-x)^(b - 1)/Beta(a,b)

<br>here, a is actually ALPHA ...
