Question
You are an engineer working for a company that synthesizes and uses polymers for a range of products. A competitor makes an identical polymer, a polypropylene, bit its properties are superior. One of the organic chemists in your company comes to you one day and and says that he has reproduced the competitor's product exactly because his polymer has the same number average molecular weight as your competitor's. Your response is:
(A) He must be demented because he is wearing a Notre Dame football T-shirt. He is also an organic chemist and cannot possibly be right.
(B) He is right even if he is demented. An average is an average and the samples must be equivalent.
( C ) He is wrong because the distribution of molecular weights could be very different.
(D) He is right because if the distributions are different then the number averages would also be different.. Also, he would only be truly demented if he was wearing a Notre Dame T-shirt.
Explain why your answer is correct.
