In the early  1990s Fuji Photo Film, USA, joined forces with four of its rivals to  create the Advanced Photo System (APS), which is hailed as the first  major development in the film industry since 35-millimeter technology  was introduced. In February 1996, the new 24-millimeter system,  promising clearer and sharper pictures, was launched. By the end of the  year, the lack of communications and a limited supply of products made  retailers angry and consumers baffled. Advertising was almost  nonexistent. Because the product was developed by five industry rivals,  the companies had enacted a secrecy agreement in which no one outside of  company management, including the company's sales force, would know  details about the product until each company introduced its APS products  on the same day. When the product was actually introduced, it came with  little communication to retailers about the product, virtually no  training of sales representatives on the product (so that they could  demonstrate and explain the features), and a great underestimation of  demand for the product. Fortunately, Fuji pressed on by taking an  "honesty is the best policy" stance and explaining to retailers and  other customers what had happened and asking for patience. In addition,  Fuji increased its research to better ascertain market positioning and  size. By 1997, Fuji had geared up production to meet the demand and was  increasing customer promotion. APS products were on the road to success.  By 1998, APS cameras owned 20% of the point-and-shoot camera market.
 Discussion
 Suppose you are a part of a Fuji team whose task it is to examine issues  about market share, customer acceptance, complaints, and the reasons  why new products are successful.
 1.	A started, by 1998 APS cameras owned 20% of the point-and-shoot  camera market. Now it is the year 2003 and the market share might be  nearer to 40%. Suppose 30 customers from the point-and-shoot camera  market are randomly selected. If the market share is really 40, what is  the expected number of point-and-shoot camera customers who purchase an  APS camera? What is the probability that six or fewer purchase an APS  camera? Suppose you actually got six or fewer APS customers in the  sample of 30. Based  on the probability just calculated, is this enough  evidence to convince you that the market share is not 40%? Why or why  not?
 2.	Suppose customer complaints on the 24-millimeter film are Poisson  distributed at an  average rate of 2.4 complaints/100,000 rolls sold.  Suppose furher that Fuji is having trouble with shipments being late and  one batch of 100,000 rolls yields seven complaints form customers.  Assuming that it is unacceptable to management for the average rate of  complaints to increase, is this enough evidence to convince management  that the average rate of complaints has increased, or can it be written  off as a random occurrence that happens quite frequently? Produce the  Poisson distribution for this question and discuss its implication for  this problem.
