Quizplus · Accepted Answer

When the sample size is 2, the lower control limit for the R-chart is not fixed at 0. It is calculated using the formula: D3 × R̅, where D3 is a constant depending on the sample size and R̅ is the average range of the two samples. Therefore, the answer is false, and the lower control limit can be greater or smaller than 0 depending on the value of D3 and R̅.
