question 26

Multiple Choice

Suppose there are 28 samples obtained at equally spaced time points, and n=7 observations in each sample. If the sum of the 28 sample ranges is 98, and that the tabulated values of $b _ { 7 }$ and $c _ { 7 }$ are 2.706 and .833, respectively, then the 3-sigma control limits LCL and UCL for an R control chart are respectively

• D) 0.0 and 37.61
• E) None of the above answers are correct.
