Q81. An X-bar chart has shown control for a long time. You see that points for the last 50 samples are all very near the center line on the chart. In fact, they are all within one sigma of the center line. This probably indicates that

It is a desirable situation.

It is an undesirable situation.

The process standard deviation has decreased during the time the last 50 samples were taken.

The control charts are incorrectly computed.

Q82. The equation below represents the:

Lognormal probability density function.

Normal probability density function.

Exponential probability density function.

None of the above.

Q83. Which of the following statements is CORRECT?

The higher the correlation, the better the regression estimate.

Regression estimates are better made with positive correlation than with negative correlation.

The lower the correlation, the greater the likelihood that homoscedasticity exists with respect to the predicted variable.

The better the regression estimate, the greater the likelihood that homoscedasticity exists with the respect to the predicted variable.

Q84. When requesting “worst case” design analysis, you expect the reliability group to

Analyze only those products failing to meet specification requirements.

Determine whether product requirements can be met with subassemblies assumed at their worst combination of tolerances.

Assume all subassembly tolerances at their maximum limit.

Normal.

Binomial.

Exponential.

The binomial or the hypergeometric distribution.

Q87. A “p” chart

Can be used for only one type of defect per chart.

Plots the number of defects in a sample.

Plots either the fraction or percent defective in order of time.

Plots variations in dimensions.

Q88. In most cases, an improvement team facilitator will NOT normally:

Be familiar with problem solving techniques.

Provide feedback to the group.

Function as the group leader.

Summarize key ideas generated by the group.

Q89. The primary advantage of the Latin square design, compared to the factorial design, is that

In most circumstances, it requires less data.

It eliminates the need for interaction analysis.

It allows higher significance levels.

It does not require homogeneity of variance.

3/4

8/9

0.840

0.625

Q94. A two-way analysis of variance has r levels for one variable and c levels for the second variable with 2 observations per cell. The degree of freedom for interaction is

2(r)(c)

(r-1)(c-1)

rc-1

2(r-1)(c-1)

Q95. Which of the following are the MOST logical reasons for providing source inspection?
I. The supplier has consistently shown poor out-going quality.
II. The key inspection points are hidden after assembly at the suppliers’ plant.
III. The supplier requests the inspection to save them potential shipping expenses.
IV. The criticality of the product warrants it.

Q96. Determine the coefficient of variation for the last 500 pilot plant test runs of high temperature film having a mean of 900 Kelvin with a standard deviation of 54.

16.7%

60%

31%

Explanation/Reference:
Explanation:
% Coefficient of Variation = S/ (X-bar) * 100
54/ 900 * 100 = 6%

Q97. Benchmarking might be defined as any of the following EXCEPT:

A process for rigorously measuring your performance versus the best-in-class companies.

A standard of excellence or achievement against which other similar things must be measured or judged.

Comparing the performance of one company to a set of standards and then to another’s performance.

The search for best industry practices that lead to superior performance.

Q98. The difference between setting alpha equal to 0.05 and alpha equal to 0.01 in hypothesis testing is

With alpha equal to 0.05, we are more willing to risk a type I error.

With alpha equal to 0.05, we are more willing to risk a type II error.

Alpha equal to 0.05 is a more “conservative” test of the null hypothesis.

With alpha equal to 0.05, we are less willing to risk a type I error.

Q99. Analysis of data on all product returns is important because
I. Failure rates change with length of product usage.
II. Changes in design and in customer use are often well reflected.
III. Immediate feedback and analysis of product performance becomes available.
