1) Below are 4 samples with 8 observations each. Using the R-Chart, determine the upper control limit for the mean.

Sample 1 Sample 2 Sample 3 Sample 4
79.1 81.7 80.5 79.4
79.8 81.5 80.2 81.2
79.7 81.1 80.8 80.2
80.7 81.2 80.4 79.5
81.2 80.9 81.8 79.0
80.2 79.8 80.9 81.6
81.3 81.3 80.1 81.3
79.6 79.0 81.6 80.1

( round your answer to 2 decimal places --> Example: 5.12 )

2) Below are 4 samples with 8 observations each. Using the R-Chart, determine the lower control limit for the mean.
