Questions # 51:

Which Experimental Design typically is most associated with the fewest number of input variables or factors in the design?

Options:

A.

Fractional Factorial design


B.

Full Factorial design


C.

Simple Linear Regression


D.

Response Surface Design


Questions # 52:

A valid Multiple Linear Regression (MLR) is characterized by all of these except _______________________.

Options:

A.

It is an assumption that the X’s (inputs) are not correlated to each other


B.

The X’s (inputs) are assumed to be independent of each other


C.

MLR is conducted based on a deliberate form of experimentation


D.

The Residuals from MLR analysis have to be Normally Distributed


Questions # 53:

For a Normal Distribution as samples size increases the Range in Mean and Standard Deviation decrease relative to the Mean and Standard Deviation of the population.

Options:

A.

True


B.

False


Questions # 54:

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

Question # 54

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 # 55:

Appropriate measures means that measurements are ______________.

Options:

A.

Representative


B.

Sufficient


C.

Contextual


D.

Relevant


E.

All of these answers are correct


Questions # 56:

SPC Charts are used extensively in different business and decision-making environments. In this example a vendor is being selected based on speed of delivery. Which of the conclusions would help you pick a vendor for your needs regarding lead-time of delivery from your vendors? (Note: There are 4 correct answers).

Question # 56

Options:

A.

Vendor A with a much shorter lead time in delivery


B.

Vendor B as it has a better consistency (lower variance) on lead time


C.

Vendor B since Vendor A shows a situation out of control as shown in red


D.

Vendor B since the Control Limits are much narrower than Vendor A


E.

Vendor B has higher lead time, but a process with much narrower Control Limits


Questions # 57:

Data that can be measured on a continuum and has meaningful decimal subdivisions are __________ data.

Options:

A.

Continuous


B.

Surplus


C.

Discrete


D.

Variable


Questions # 58:

Cost of Poor Quality (COPQ) can be classified as Visible Costs and Hidden Costs. All these items are Hidden Cost except __________________.

Options:

A.

Lost Customer Loyalty


B.

Returns


C.

Time Value of Money


D.

Late Delivery


Questions # 59:

Situations where standardized work needs to be incorporated include all of these except _____________________.

Options:

A.

Changeover instructions incomplete


B.

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


C.

Machines continually operating to reduce the labor cost per piece


D.

Process flow for the same product assembly taking various cycle time for completion


Questions # 60:

Sally and Sara sell flower pots at their garage sale. Sally motivates Sara mentioning that they will sell a minimum of 15 pots per day if the outside temperature exceeds 60o F. From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots. The statistical Degrees of Freedom for this example are?

Options:

A.

1


B.

29


C.

30


D.

31


E.

2
