(Continuous random variable) Impurities in the batch of the final product of a chemical process
often reflect a serious problem. From a considerable amount of data collected at the plant it is
known that the proportion of impurities (Y) in a batch has a density function given by:
= {10(1-y)⁹
f(y):
0 ≤ y ≤ 1
en otro caso
The lot is considered unsaleable, and therefore, is not acceptable if the percentage of
impurities is higher than 60%.
a. Verify that the above function is indeed a probability density function.
b. Calculate the probability of rejecting a lot due to impurities.
c. Calculate the expected value of impurities in the batch.
d. Assume that the lot sells for $792 and you have to pay operating expenses of $50 for the lot.
Calculate the expected profit.
e. Calculate the standard deviation of the impurities in the lot and the profit.
