Question No.61
Which statement(s) are correct about the Factorial Plot shown here? (Note:There are 3 correct answers).

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

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

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

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

These plots are an example of interaction plots.
Correct Answer: ABC
Question No.62
Situations where standardized work needs to be incorporated include all of these except
.

Machines continually operating to reduce the labor cost per piece

Lack of a system to assure proper inventory levels at repair stations

Changeover instructions incomplete

Process flow for the same product assembly taking various cycle time for completion
Correct Answer: A
Question No.63
A Factorial Experiment based on a Level 2 Design with 6 factors would require 16 runs to fully assess the interactions.

True

False
Correct Answer: B
Question No.64
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?

The Standard Deviation is equal to $300.

The Mean is less than $4,320.

The Mean is equal to $4,060.

The Mean is less than $4,200.

The Mean is greater than $ 4,200.
Correct Answer: E
Question No.65
To establish a sample size that will allow the proper overlap of distributions we do which of these?

Multiply Alpha by 1.75

Calculate one minus Beta

Calculate Beta plus 2

Multiply Beta by 3
Correct Answer: B
Question No.66
Upon completion and validation of an improvement to a process a Belt and the Project Team create a Control Plan that contains which of these?

Standard operating work description of the process change

Description of the monitoring system in place to assure continued compliance

Summary of the targeted critical metrics for process performance measurement

All of the above
Correct Answer: D
Question No.67
A Personal Trainer was assessing her workout class participants for their body fat content and had to include data for her analysis. One of the columns listed the range of weight of the people included in the studies. This required plotting a Histogram of the weight of the people assessedfor their body fat content. While drawing the Histogram the xaxis contained a certain scale of data. Pick the scale of data that is appropriate for Histograms.

Ordinal Scale Data

Ration Scale Data

Nominal Scale Data

Interval Scale Data
Correct Answer: D
Question No.68
Which statement(s) are most correct for the Regression Analysis shown here?

The Regression explains 50.8% of the process variation

The airfuel ratio explains most of the TurbineOutput variation

This Simple Linear Regression explains 98 % of the process variation

This Multiple Linear Regression has four statistically significant independent variables
Correct Answer: B
Question No.69
For the data shown here which statement(s) are true? (Note:There are 2 correct answers).

With 95% confidence, we cannot conclude if the samples are from three Normal Distributions

With greater than 95% confidence, we conclude the samples are from Nonnormal Distributions

If we wanted to compare the Central Tendencies of these three samples we would use the one way ANOVA test

If we wanted to compare the Central Tendencies of these three samples we could use Mood#39;s Median test

If we wanted to compare the Central Tendencies of all three samples we could use the Mann Whitney test
Correct Answer: BD
