Reference no: EM13977581

Telemarketers for a mail-order firm are assigned to make a total of 200 calls each day, then record the number of potential customers who are interested in receiving a catalog and first-order discount coupon in the mail. For each of the past 50 days, the number of catalog/coupon packages sent is as shown here. Construct one or more appropriate control charts and comment on the state of control of the process.
