Question No.243

The Normal Distribution is considered to be the most important distribution in statistics and, among other things is defined as having a total area under the curve of 1, is mounded and symmetrical and the Mean, Median and Mode are .

1. All evenly divisible by 3

2. Twice the Standard Deviation

3. Within 10% of each other

Correct Answer: D

Question No.244

In a good Measurement System the most variation will be with part-to-part measurements. What should you do if the majority of variation is associated with the Gage Ramp;R assuming the gage is technically capable?

1. Focus on fixing the Repeatability and Reproducibility of the measurement device

2. Purchase a new machine

3. Focus on trimming the Part-to-Part variation

4. Run another MSA test with the machine

Correct Answer: A

Question No.245

With Measurement System Analysis we are concerned with two issues that impact the potential variability of the data. They are and Accuracy.

1. Spread

2. Reliability

3. Precision

4. Deflection

Correct Answer: C

Question No.246

Which statement(s) are incorrect about Fractional Factorial Designs?

1. A Half Fractional Design for 5 factors has the same number of experimental runs as a Full Factorial Design for 4 factors assuming no repeats or replicates or Center Points

2. Quarter Fractional experiments can exist for those with 4 factors

3. Resolution V design is desired while controlling costs of experimentation

4. Half Fractional experiments do not exist for those designs with only 2 factors

Correct Answer: C

Question No.247

Which statement(s) are correct about the Factorial Plot shown here? (Note:There are 3 correct answers).

1. When the cutting speed increased from low to high level, the tool age increases

2. The coefficient of the metal hardness is positively related to the output of tool age

3. The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool age

4. These plots prove a statistically significance factor with 95% confidence

5. These plots are an example of interaction plots

Correct Answer: ABC

Question No.248

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.

1. True

2. False

Correct Answer: B

Question No.249

Using this partial Z Table, how many units from a month#39;s production run are expected to not satisfy customer requirements for the following process?

1. 8

2. 13

3. 28

4. 57

Correct Answer: D

Question No.250

A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt#39;s effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of

$98 was estimated. The Alternative Hypothesis in the above example is?

1. The Standard Deviation is equal to $300

2. The Mean is less than $4,320

3. The Mean is equal to $4,060

4. The Mean is less than $4,200

5. The Mean is greater than $ 4,200

Correct Answer: E
