The proper order of steps in a Six Sigma project is

In a normal distribution, what is the area under the curve between +0.8 and +1.7 standard deviation units?

A standard Z table is used to determine the area under the curve. The area under the curve represents probability.

A distribution is considered normally distributed is the P-value is less than .05

What is the value of Z in the normal tables that has 3% of the area in the tail beyond it?

The prime use of a control chart is to
