1) When only thevalue-added time isconsidered, the time it takes to build a laser printer is thought to be uniformly distributed between 8 and 15 hours.

a. What are the chances that it will take more than 10 value-added hours to build aprinter?

b. How likely is it that a printer will require less than 9 value-added hours?

c. Suppose a single customer orders two printers. Determine the probability that the first and second printer each will require less than 9 value-added hours to complete.

2) A survey reported that 38% of people plan to spend more on eating out after they retire. If 9 people are randomlyselected, determine the values below.

b. The standard deviation of the individuals who plan to spend more on eating out after they retire

c. The probability that two or fewer in the sample indicate that they actually plan to spend more on eating out after retirement

3) The mean number of errors per page made by a member of the word processing pool for a large company is thought to be2.5with the number of errors distributed according to a Poisson distribution. If a page isexamined, what is the probability that more than two errors will beobserved?
