Transcribed Image Text:6.12. The net weight (in oz) of a dry bleach product is to
be monitored by ī and R control charts using a sam-
ple size of n = 5. Data for 20 preliminary samples
are shown in Table 6E.7.
(a) Set up ī and R control charts using these data.
Does the process exhibit statistical control?
(b) Estimate the process mean and standard deviation.
(c) Does fill weight seem to follow a normal distri-
bution?
(d) If the specifications are at 16.2 ± 0.5, what
conclusions would you draw about process
capability?
(e) What fraction of containers produced by this
process is likely to be below the lower specifi-
cation limit of 15.7 oz?
