From the process which fills boxes of granulated product, the weights of the boxes are evaluated in consecutive subgroups of size n = 4. After collecting 40 subgroups the following summary statistics were calculated: X (with a double bar above it) = 1.15, and R (with a bar above it) = 0.03.. What are the lower and upper control limits for the R-Chart?
A. 0.0069 and 0.05331
B. 0.05934 and 0.06177
C. 0 and 0.06846
D. 0 and 0.06798
