4 Iron ore is dug up to be crushed and filtered through a sieve prior to further processing. The sieve filters out any iron ore larger than lem in diameter. Let X be a random variable describing the diameter (in cm) of a piece that has made it through the sieve. Suppose that X has the beta distribution with parameters a = 4 and ß = 3. (a) Determine the cdf of X. (b) Calculate the mean and standard deviation of the diameter of iron ore pieces. (c) The dollar value V of an iron ore piece is proportional to its volume, specifically V = $ 5X³. Find E[V], the average dollar value of a piece that makes it through the sieve.

4 Iron ore is dug up to be crushed and filtered through a sieve prior to further processing. The
sieve filters out any iron ore larger than lem in diameter. Let X be a random variable describing
the diameter (in cm) of a piece that has made it through the sieve. Suppose that X has the
beta distribution with parameters a = 4 and 3 = 3.
(a) Determine the cdf of X.
(b) Calculate the mean and standard deviation of the diameter of iron ore pieces.
(c) The dollar value V of an iron ore piece is proportional to its volume, specifically V = $ 5X3.
Find E[V], the average dollar value of a piece that makes it through the sieve.
