The control charts are used to study the changes in process over a time. There are control limits in the graph plotted with the help of the data and if at any time it crosses those limits i.e. upper limit or lower limit then the process is out of control.
In this case, a company uses control charts to monitor the performance of its process. In the morning’s shift, the process was judged to be in control. This means that the data has not crossed the upper control limit nor the lower control limit.
There are assignable causes of variation. (ANSWER)
[A cause of variation that does not occur by chance or not random is “assignable”. Therefore, this is possible.]
The variation in units is considered natural [The variation above upper control limit and lower control limit means the process is out of control.]
The units produced by this process satisfy customer specifications [We are here talking about the company and its specifications are not known – so cannot comment.]
There was no variation in units produced by this process [This is not necessary if there are variations but in limit of upper control limit and lower control limit then also the process is in control.]
