Five samples of size 5 were taken from a process. A Range chart was developed that had LCLR = 0 and UCLR = 5.50. Similarly, a Process Average chart was developed using the measurements from the five samples, with LCLx = 25.0 and UCLx = 40.0. The ranges for each of the five samples were 3.75, 2.42, 4.75, 2.04, and 5.80, respectively. The values of the sample average for each sample were 29.5, 27.3, 37.4, 26.1, and 28.9, respectively. What can you tell management from this analysis?

Group of answer choices

The process variability is out of control

The process average is out of control

Both the process variability and the process average are out of control

We cannot tell if the process variability or the process average is out of control
