1) The Chair of the Quality Department at Motorola University wants to construct a p-chart for determining whether the four faculty members teaching the course are in a state of control concerning the number of students who fail in the course. Accordingly, the Chair sampled 500 final grades from last year for each instructor, and computed the number of failures per instructor as 13, 11, 0, and 16 respectively. Compute the upper and lower standard control limits for this chart.
a) 0.9500 and 0.0500
b) 0.0600 and 0.1400
c) 0.0388 and 0.0012
2) In general, viable scientific exploration:
a) Is conducted to prove old truths are infallible
b) Is conducted to create a falsifiable model that is able to predict future outcomes
c) Relies on anecdotal evidence to support its claims
d) Is conducted to create models that are unable to predict future outcomes
3) Referring to the product-process matrix, if a company has a few major products with high demand and a jumbled flow (job shop) process, we know the company:
a) Has a company strategy
b) Is on the diagonal of the matrix
c) Is further in its process life cycle than its product life cycle
4) A company has been working a six-sigma program for several years, with a focus on improving yield on a key process. Prior to the program, the typical yields were averaging 70%. Presently, yields are consistently above 95%. This will allow the company to: I. Increase price for the product II. Reduce their process buffers III. Eliminate all special cause variation
b) I and II
c) III only
d) I only
e) II only
5) It is generally easier to make changes in: a) Your area of influence b) Your area of control c) To upstream areas
