Six Sigma focuses on improving business performance by

reducing variation

Who are the Quality Gurus?

Dr. Joseph M. Juran, Dr. Edwards Deming, Dr. Armand V. Feigenbaum

Which company used Lean manufacturing first?

Toyota

The NBC documentary "If Japan Can....Why can't we? was first aired in

1980

Which company used Six Sigma first?

Motorola

Who proposed to combine Lean and Six Sigma?

Michael George

Who taught Japanese quality control?

Edwards Deming

Total quality cost consists of two parts:

cost of failure and cost of appraisal/prevention

Effective Total Quality Management (TQM) practices lead to

the lowest possible Cost of Quality (CoQ)

The four belts in the ASQ Six Sigma certification system are in the following order

Yellow Belt, Green Belt,Black Belt, Master Black Belt

The experiment is defined as tossing a fair coin two times. What is the sample space.

{{H,H},{H,T},{T,T},{T,H}}

The experiment is defined as tossing a fair coin two times. Which of the following is a simple event?

{{H,H}}

The experiment is defined as tossing a fair coin two times. Which of the following is a compound event?

All the above
a) {{H,H},{H,T}}
b){{T,T},{H,H}}
c){{H,T},{T,H}}
d){{H,H},{H,T},{T,T}}

The experiment is defined as tossing a fair coin two times. What is the probability of having head two times?

0.25

In Example 2.1 of the textbook, if the tolerance of resistance is reduced to 2.5% and the tolerance for capacitance is reduced to 10%, recalculate the worst case scenario cut-off frequencies(in Hz)

141.23 and 181.47

Given two sets:
A = {1,2,3,5,7}
B = {1,5,7,9}
What is the expected result of: A & B

{1,5,7}

Given two sets A = {1,2,3,5,7} and B={1,5,7,9}, find AUB.

{1,2,3,5,7,9}

The sample space is {1,2,3,4,5,6,7}. An event A is defined as A = {1,2,3}. The complement of A is

{4,5,6,7}

A = {1,2,3}, B={2,3,4}. Then A and B are mutually exclusive

False

A Six Sigma level process has ____ detective part per million opportunities

3.4

Defects are the ones outside of the Lower Specification Limit (LSL) and the Upper Specification Limit (USL).

True

To draw a conclusion about the entire population from a given set of data, we are using

statistics

Which polling method is better for US presidential elections:

Stratified sampling

The following formula is always true:
P(AUB) = P(A)+P(B)-P(A)P(B)

False

Two independent subsystems A and B are connected in series, then the overall system S has the probability of being a success P(S)=

P(A)*P(B)

Probability

The relative possibility that an event will occur, as expressed by the ratio of the number of actual occurrences to the total number of possible occurrences. To predict the results of experiments based on the characteristics of population.

Statistics

the science of collecting, organizing, analyzing, and interpreting data in order to make decisions

Population

a well-defined collection of objects that are of interest in a specific case

Census

if all the information for all objects in the population is available,

Sample

a subset of the population

experiment

any activity having uncertain outcomes

sample space

of an experiment, denoted by ohm: is the set of all possible outcomes of that experiment

event

any collection(subset) of outcomes contained in the sample space

simple event

an element in a sample space that consists of a single outcome

compound event

An event made up of two or more simple events or contains more than one outcome

simple random sampling

assigns any particular subset of a given size the same chance of being selected(Example 2.3 polling for a local mayoral race)

Stratified sampling

first divides the entire sample space, into non-overlapping subsets, followed by simple random sampling with each subset(Example 2.4 polling for the U.S presidential election)
