3.​New Process, Inc., a large mail-order supplier of women’s fashions, advertises same-day service on every order. Recently, the movement of orders has not gone as planned, and there were a large number of complaints. Bud Owens, director of customer service, has completely redone the method of order handling. The goal is to have fewer than five unfilled orders on hand at the end of 95% of the working days. Frequent checks of the unfilled orders follow a Poisson distribution with a mean of two orders. Has New Process, Inc. lived up to its internal goal? Cite evidence.

b.​What is the likelihood that in the sample of three at least one Honda is included?
5.​According to the “January theory,” if the stock market is up for the month of January, it will be up for the year. If it is down in January, it will be down for the year.
