As we can see in Median chart there are two readings which are not in control limit i.e, one is above upper control limit and one is below lower control limit. So these two values can be excluded.
And if we see R chart we see that two values are above upper control limit and so these values can be eliminated.
Exercise 8 :
Transactional: One paid invoice was randomly selected each day. The number of days past the invoice due date was tracked using an XmR chart.
