Black Belt W24 Certification Review

An Invoice Operation is investigating their error rate. The first step should be to

In a particular process, 500 orders were submitted, of which 50 contained errors.Of the 50, 35 were corrected and reprocessed. The Throughput Yield for this process step is:

The Define Stage of DMAIC is

A frame is

The basic premise of Six Sigma is that sources of variation can be:

The Throughput Yield for six departments processing an order in series is as follows: 99.7%, 99.5%, 95%, 89%, 92.3%, and 94%. The probability of no defects acress all steps (rolled throughput yield) is:

A Six Sigma level of quality:

What are the key "Critical to Quality" areas?

The benefits of a process map would include:

In a process, the upper and lower control limits are determined by:

The area under a normal curve to the right of the mean represents:

Special Cause variation is random, expected variation

A Process has seven critical characteristics, in a sample of 1,000 orders the number of opportunities for defects used in calculating DPMO is:

When every item has equal probability of being selected, the sampling strategy used is called

Specification limits are established by

If a distribution is positively skewed, the mean will be

The concept of a "dashboard" is to

Manually calculate the standard deviation of the following sample set of data:52, 20, 24, 31, 35, 42

In developing a SIPOC, a Black Belt is concerned with documenting a process at a high level. The major components include

The SIPOC is used to

Six Sigma objectives are to

If a distribution is positively skewed the median will be

Calculate the Standard Deviation of the following population data:50, 20, 35, 15

A process produces 350 orders, of which 50 contained errors. Of the 50, 35 were corrected and processed. The yield for this process is

Which is not a step in developing a Cause and Effect Matrix?

Caluclate the z-value given the following information: u=100, r=5, and the Point of Interest or the USL equals 125

The FMEA requires a Risk Priority Number (RPN) to be calculated. The RPN is the product of which 3 rankings:

Determine the total area under the curve to the left of the Z-score = 0.86

Assuming that the average number of days an account receivable is on the books until funds are received is 30 days with a Standard Deviation of 4 days. How many days does it take until 40% of the Accounts Receivables have been paid?

In a control chart, the upper and lower control limits are determined by

The variation that results when different conditions are used to make the measurements is classified as

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

Universities and colleges have classifications of freshmen, sophomores, juniors, and seniors; these are examples of which data type:

A process that is in statistical control would be a process that would always meet customer specifications

You will be checking 40 valves a day for defects. You will record the defects for 30 consecutive weeks. Which control chart will you use?

You inspect 100 credit applications a day. It is either correct and you can pass it through or it is incorrect. The control chart that you want to use is:

One of the benefits of using either the p-chart or the u-chart is that they both can be used with

When collecting data for creating a control chart, it is important to
