A population of size 1,000,000 has mean 42 and standard deviation 6. Sixty random samples, each of size 15 are selected. According to the Central Limit Theorem the distribution of the sixty sample means has a mean of approximately:
After a team has engaged in diversion activities they may need to employ a tool for conversion. Examples of such a tool are:
1. nominal group technique
2. multivoting
3. cause and effect diagram
4. activity network diagram
5. matrix diagrams
The following is a set of individual measurements:
3 5 4 5 6 3 4 3 2 4 5 6 5 7 6 4 5 5 8 7 6 6 7 7 4
Find the control limits for the range chart.
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.

Find the equation of the regression line for these sample data points:
(1, 7) (3, 3) ( 3, 2) (5, --1)
