Questions # 11:

A Lean Six Sigma project is attempting to reduce inventory days. The Process Capability will be monitored as part of the Control Phase to track the sustainability of the improvement.

Question # 11

Which distribution type is best used for performing the Capability Analysis?

Options:

A.

Weibull Distribution

B.

Normal Distribution

C.

Exponential Distribution

D.

Logistic Distribution

E.

Gaussian Distribution

Questions # 12:

An operator checks that all boxes being packed contain enough products to fill the box. However, each box getting filled has a different number of products in it. This is a Reproducibility problem, not a Repeatability problem.

Options:

A.

True

B.

False

Questions # 13:

What conclusion is most correct about the Experimental Design shown here with the response in the far right column?

Question # 13

Options:

A.

No factor has enough statistical confidence greater than 95% to have an impact on the response rate

B.

Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more

C.

If the Adv is increased from the low level to the high level, the response rate increases

D.

The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate

E.

This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output

Questions # 14:

Time is always the metric on the horizontal scale of a(n) ___________ Chart.

Options:

A.

Pareto

B.

Xbar

C.

Multi-Vari

D.

NP

Questions # 15:

Options:

A.

Histograms

B.

SPC Charts

C.

NP Charts

D.

Pareto Charts

Questions # 18:

Options:

A.

Correlation Analysis

B.

Gage R & R

C.

Bimodal

D.

Dual Attribute

Questions # 19:

Options:

A.

Data shift analysis

B.

Outlier analysis methods

C.

Center Line and Control Limits

D.

None of the above

Questions # 20:
