# I have twelve questions that I will just pay a flat amount ...

### Customer Question

I have twelve questions that I will just pay a flat amount for if I can receive help on them. 1. True or false: Concluding a process is out of control when it is not is know as Type I error?
2. T of F: Larger samples will require wider x-bar control limits because there is more data?
3. T or F: A c chart is used to monitor the total number of defectives in the output of a process.
4. T or F: Range control charts are used to monitor process central tendency?
5. EWNA chart is often preferable to the traditional x-bar chart for detecting small mean changes of a process?
6. T or F: The idea of rational subgroup is that each subgroup is selected in such a way that it has maximum chance of detecting common cause variation within the subgroup, and the minimum chance of detecting special cause variation between subgroups?
The next set of problems are multiple choice.
7. A control chart used to monitor the fraction of defectives generated by a process is the
a. x-bar chart
b. R-chart
c. p-chart
d. c-chart
e. MR-chart
8. A control chart used to monitor the number of defects per unit is the
a. p-chart
b. R-chart
c. x-bar chart
d. c chart
e. MR-chart
9. A point which is below the lower control limit on an R-chart:
I.   should be ignored since lower variation is desirable
II. may be an indication that process variation has decreased
III. should be investigated for assignbale cause

a.     I and II
b.     I and III
c.     II and III
d.     II only
e.     I, II and III
10. The purpose of control charts is to:
a. estimate the proportion of output that is acceptable
b. weed out defective items
c. determine if the output is within tolerance/specifications
d. distinguish between random (common) variation and assignable (special) variation in the process
e. none of the above
11. Moving range chart may be used for variable data with no subgroups but only available individual values. The potential problems with moving range chart are:
I.   moving ranges are correlated
II.   unable to use control char constants to estimate standard deviation
III. control limits may be inflated
a.     I and II
b.     I and III
c.     II and III
d.     I, II and III
e.     None of the above
12. The term “2-sigma limits” in the context of a control chart refers to the variability of the
a. process
b. population
c. sample
d. sampling distribution
e. standard deviation
