Q1. A Quality Analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results:

Machine	Measurements
#1	17	15	15	17
#2	16	25	18	25
#3	23	24	23	22

Using the factors for three sigma control limits, what are the sample range (R) chart upper and lower control limits?

Select one:

a. 11.14 and 0

b. 4.33 and 0

c. 4.94 and 0

d. 8.66 and 0

e. 9.88 and 0

Q2. The Chair of the Operations Management Department at Quality University wants to construct a _control _chart for determining whether the four instructors teaching the basic P/OM course are under control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results:__INSTRUCTORNUMBER OF FAILURESProf. A13Prof. B0Prof. C11Prof. D16What are the .95 (5% alpha risk) upper and lower control limits for the _p_-chart?

a. x = 2, y = 1

b. x = -1, y = 1

Q4. Given the following historical data and weights of .5 for the most recent period, .3 for the next most recent, and .2 for the next after that, what is the weighted three-period moving average forecast for period 5?

Period	Value	Period	Value

c. x = 1, y = 5

d. x = 2, y = 8

e. x = 4, y = 4

Q5. Which one is True?

Select one:

a. A p-chart is used to measure shifts in process dispersion.

b. ample range control charts are used to measure shifts in the process mean.

c. If a point on a control chart falls outside one of the control limits, this suggests that the process output is non-random, assignable variation.

d. Attributes are process characteristics that must be measured rather than counted.

e. A _c_-chart is used to monitor the number of defectives in the output of a process.

Q6. Which one is correct?Select one:

Select one:

a. ISO 9002 is an international standard for assessing a company's environmental performance.

b. Suppliers are partners in TQM and should be included in quality improvement efforts.

c. Quality control tends to be a proactive approach to quality management.

d. A control chart is a visual representation of the key steps in a process.

e. A benchmark organization must be chosen from the same industry in order for its methods to be applicable.
