Quizplus · Accepted Answer

A c-chart is a control chart used to monitor the count of defects per unit of output. In this case, the supplier is counting the number of blemishes on each silicone sheet, which makes the c-chart the most appropriate analysis to perform. Autoregressive modeling, exponential smoothing, and multiple linear regression are not appropriate for monitoring counts of defects.
