Question

Impurities in batches of product of a chemical process reflect a serious problem. It is known that the proportion of impurities Y in a batch has the following density function. Complete parts (a) through (e) below.\\ $f(y) = \begin{cases} 10(1-y)^9, & 0 \le y \le 1, \\ 0, & \text{elsewhere} \end{cases}$\ (c) What are the parameters $\alpha$ and $\beta$ of the beta distribution illustrated here?\\ $\alpha = $\\ (Type an integer or a decimal. Do not round.)\\$\beta = $\\ (Type an integer or a decimal. Do not round.)\\ (d) The mean of the beta distribution is $\frac{\alpha}{\alpha + \beta}$. What is the mean proportion of impurities in the batch?

Impurities in batches of product of a chemical process reflect a serious problem. It is known that the proportion of impurities Y in a batch has the following density function. Complete parts (a) through (e) below.

f(y) = 10(1-y)^9, 0 ≤ y ≤ 1,
0, elsewhere(c) What are the parameters α and β of the beta distribution illustrated here?

α =

(Type an integer or a decimal. Do not round.)
β =

(Type an integer or a decimal. Do not round.)

(d) The mean of the beta distribution is (α)/(α + β). What is the mean proportion of impurities in the batch?
