Five samples of size 4 were taken from a process. a range chart was developed that had

lclr

= 0 and

uclr

= 2.50. similarly, an average chart was developed with the average range from the five samples, with

lcl

= 15.0 and

ucl

= 22.0. the ranges for each of the five samples were 1.75, 2.22, 2.35, 2.04, and 2.30, respectively. the values of the sample average for each sample were 19.5, 22.3, 17.4, 20.1, and18.9, respectively. what can you tell management from thisanalysis?

a.

the process variability is out of control, and we cannot make a statement about the process average.

b.

the process variability is in control, but the process average is out of control.

c.

the process variability and the process average are in control.

d.

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