Given the following X-bar and Range control charts for a dimension with Specification of 3.5 +/- 0.5, which of the following may be reasonably concluded from the information provided? Additional Information: Subgroup size = 5; Total Sample Size (N) =100; From Range Chart, R-bar = 0.924; Grand Mean = 3.510; Data are normal with sample standard deviation = 0.4 Xbar-R Chart of Response 4.00 3.75 Sample Mean 3.50 X=3.510 3.25 3.00- 11 13 15 17 19 Sample 2.0 1.5 Sample Range 1.0 R=0.924 0.5 0.0 9 11 13 15 17 19 Sample O a. Calculations for Ppk will be significantly larger than Cpk (at least 0.5 larger) O b. Calculations for Ppk will be significantly smaller than Pp (at least 0.5 smaller) O c. Calculations for Ppk will not significantly differ than Cpk (i.e., Ppk ~ Cpk) O d. Calculations for Pp will be significantly larger than Cp (at least 0.5 larger)
