Question 11five Samples Of Size 4 Were Taken From A Process The Ran Question 11five Samples Of Size 4 Were Taken From A Process The Ran QUESTION . Five samples of size 4 were taken from a process. The ranges for each of the five samples were 1.75, 2.42, 2.75, 2.04, and 2.80, respectively. The values of the sample average for each sample were 19.5, 20.3, 18.4, 20.1, and 18.9, respectively. What can you tell management from this analysis? Answer Both process variability and process average are in control The process variability is out of control, and we cannot make a statement about the process average. The process variability is out of control, but the process average is in control. 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. 5 points QUESTION .
