A large distribution center of a package delivery company had an average of 2.5 major conveyor jams in each sort.  (A sort is when the semi-trucks bring packages to the facility and they are sorted to put into vehicles going to other centers or the final customer.  The sort uses a massive number of conveyors.)  The center runs 3 sorts per day.  Assuming the number of major jams follows a Poisson distribution, what is the probability of having exactly 5 major jams on a day?

Implementing actions to sustain enhancements made to a process is a key occurs in which phase of DMAIC?

Reliability analysis of many aeronautical mechanical components is often performed using the lognormal distribution.  If the number of cycles of use before failure of a component follows a lognormal distribution with parameters µ= 15 and σ = 4.5.  What is the probability that the component will fail in less than 1000 cycles?

In considering the cost of quality, which of the following would be NOT be considered an activity associated with internal failure costs?

A sample in which the population is divided into groups, then observations are taken at random from each group is called a

Reliability analysis of many aeronautical systems components is often performed using the lognormal distribution.  If the number of cycles of use before failure of a component follows a lognormal distribution with parameters µ= 14 and σ = 4.6.  What is the probability that the component will fail in less than 1400 cycles?

Which of the following shows a positively skewed distribution?

A process characteristic follows a normal distribution with a mean of 25.15 and standard deviation of 0.9.  The spec limits for the characteristic are 25.00 +/- 1.5.   If a sample of 8 parts are taken from the process, what is the probability that there will be no parts out of spec in the sample?

A process characteristic has a mean of 140 and standard deviation of 5.5.  Above what value will 80% of the observations fall?
