The concentration of an active ingredient in the output of a chemical reaction is strongly influenced by
Question:
(a) Does this sample information with an average concentration of
provide disturbing in-formation that perhaps μA is not 65%, but less than 65%? Support your answer with a probability statement.
(b) Suppose a similar experiment is done with the use of another catalyst, catalyst B. The standard deviation Ï is still assumed to be 5% and XÌ
B turns outto be 70%. Comment on whether or not the sample information on catalyst B strongly suggests that μB is truly greater than μA. Support your answer by computing
(c) Under the condition thatμA = μB = 65%, give the approximate distribution of the following quantities (with mean and variance of each). Make use of the Central Limit Theorem.

The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
