A randomized block design with 4 treatments and 5 blocks produced the following sum of squares values: SS(Total) = 1,951, SST = 349, SSE = 188 . The value of SSB must be:
 a. 537
  b. 1,763
  c. 1,414
  d. 1,602

Question 2

Suppose you are producing a product implementing statistical process control.
 a. Give an example of assignable variation that would create a level shift.
  b. Give an example of assignable variation that would create instability.
  c. Give an example of assignable variation that would create a trend.
  d. Give an example of assignable variation that would create a cycle.

Answer to Question 1

C

Answer to Question 2

a. Machine breakdown, new machine and/or operator, or a change in environment, such as temperature or humidity can create a level shift.
b. A machine in need of repair, defective materials, wear of tools, or a poorly trained operator can cause instability.
c. Less than regular maintenance, including operator fatigue, residue or dirt buildup, a gradual loss of lubricant in a machine can cause a trend.
d. Cyclical chances in environment (for example night vs. day temperature) or a change in operators every 8 hours can cause cyclic variation.
