P(A) = .42, P(B) = .58, P(A&B) = .10. Are A and B (statistically) independent?
A quality engineer employed by a hospital is asked to improve the process of medication storage in locked cabinets near patient doors. One defect that occurs rarely is that the medication caddy is left out when the cabinet is relocked. The engineer installs a gravity activated arm that will not permit the door to close when the caddy isn’t inside.
This improvement is best described by which approach to problem solving?
(Refer to the previous problem) To estimate the within treatment variance the experimenters would calculate the variances of:
Find the value of (9) in the ANOVA table. Assume:
The word “champion” in the context of Six Sigma projects refers to:
The support for an important quality initiative was lacking in congress until Reagan’s Secretary of Commerce was killed in a horseback riding accident in 1987. That initiative was:
A team studies a coil steel banding process and makes five changes resulting in productivity improvements of 2%, 2.8%, 2.4%, 2% and 3% respectively. These improvements are best described by which approach to problem solving?
The term “expected value” is closest to the term:
Find the value of (4) in the ANOVA table. Assume:
SCENARIO A Six Sigma team is measuring the moisture content of corn starch as it leaves the conveyer belt of a dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locations labeled A, B, C, and D across the end of the belt. See the diagram below.
The data for a nine hour period are:
Which type of variation dominates? (Hint: Plot the points on the graph above.)
