A team’s goal is to improve information flow in a payroll function. They make thirtythree PostIt® notes, each listing an issue for further investigation. After some discussion, they group them into four categories: mandated record keeping, privacy concerns, insurance concerns and transfer concerns.
This grouping process is best described by which approach to problem solving?
A sample of size 50 from machine A has a mean of 18.2 and standard deviation 3.1. A sample of size 40 from machine B has mean 17.6 and standard deviation 2.8. Do these data indicate that the population for machine A has a larger mean? Assume the populations are normal.
The median is a better choice than the mean for a measure of central tendency if the data:
There are 14 different defects that can occur on a completed time card. The payroll department collects 328 cards and finds a total of 87 defects. DPU =
A team wants a technique for obtaining a large number of possible reasons for excess variation in a dimension. They should use:

A team wants a technique for doing an initial study of a process that not every team member is familiar with. They should use:
A management team lists nine goals across the top of a rectangle and 15 activity initiatives along the left hand side of the rectangle. If one of the activities strongly supports one of the goals a circle is placed in the box where that activity’s row intersects the goal’s column. If the activity’s support is very strong a “bulls eye” is placed in the box and if the support is weak a triangle is used.
