Any help on this control chart question?

Q:A production process has been defined as part of an industrial equipment
manufacturing project.The process is intended to produce steel bolts with a
length of 20 cm.The acceptable control limits are 19.955 cm and 20.045 cm.
The measurements made at the end of the process yielded the following
results:
20.033 cm, 19.982 cm, 19,995 cm, 20.006 cm, 19.970 cm, 19.968 cm,
19.963 cm, 19.958 cm, 19.962 cm, 19.979 cm, 19.959 cm.
What should be done?
A. The process is under control.It should not be adjusted.
B. The process should be adjusted.
C. The control limits should be adjusted.
D. The measuring equipment should be recalibrated

 

Ans is . B: The process should be adjusted.

Can pls soemone explain why?bcoz all the results are within control limit.So i was choosing option A.

Since there are seven(7) control points on one side of the mean it is termed as out of control. Hence, Answer B

7 consecutive results

I prefer to be an independent traveler. It's quite good fun to go alone and just meet people on the way. It also is a good way to grow up and to seriously learn responsibility. But this Easter holiday I will make an exception, I will go with my family to spend the Easter Mass in Strasbourg.
 

I totally agree with the above answer “Since there are seven(7) control points on one side of the mean it is termed as out of control. Hence, Answer B,” since there are consecutive results presented. Follow the link and you'll see why this is the answer. 

Hi The answer is be, apply the 7 special casues rule here. if you llom at the question, the below score on control chart are plotted on one side between mean & LCL. the count is seven so 7 special causes apply to this question.


19.970 cm, 19.968 cm,19.963 cm, 19.958 cm, 19.962 cm, 19.979 cm, 19.959 cm.

agree with the above justificstion. rule of seven applies .  mean of the above control limits is 20.00 and the seven consecutive data are between 19.955 and 20.000.

It needs to be investigated. The answer is B

When 7 consecutive measurements lie on one side of mean. Which is what the case here. So there needs to be an assignable cause. For rule of seven, or for measurements outside control limit, there are usually reasons behind that cannot be predicted. These causes can be prevented. Hence it requires that this be looked at, and the process be adjusted after addressing the assigned cause.

By applying 'rule of seven' the process is out of control and it need adjustment.'Rule of seven' tells us that if there is seven consecutive measurements on either side of the mean,then the process is out of control.Answer is 'B'

I see there ae some measurements on the other side of mean...AM I seeing something wrong?

rule of seven applies - So the Answer is B

 this is not in accordance with the sum and substance of rule of seven. If I have to go by the flawed logic being discussed/enforced here, in any case more than 14 measurements (with no one lying exactly on mean) will lead to rule of seven

Want more people to throw light on this. For me this process is in Control.
