Question

Quizplus · Accepted Answer

The R-chart (Range Chart) would be the best choice for monitoring the variability in the weight of the fertilizer bags. The R-chart measures the range (difference between the highest and lowest values) within a sample, providing a measure of the variability within the process. This chart is particularly useful when the mean of the process shifts often or is not applicable, as is the case with weight measurements. The other options, $\bar { X }$ -chart, p-chart, and c-chart, are not appropriate for monitoring variability in weight measurements.
