Question

The chart given to the right summarizes the complaints received at a catalog sales call center by day of the week. The chart shows percentages for each day. The complaints are classified as related to delivery (the order has not arrived), fulfillment (an item was missing from an order or was not what was ordered), size (an item did not fit), and damage. Complete parts (a) and (b).

(a) Is the day of the week associated with the nature of the complaint? Explain why you think these variables are or are not associated.

A) No, the day of the week does not appear to be associated with the nature of the complaint. The category percentages are not consistent on different days. For example, the percentage of complaints about delivery is much greater on Fridays.
B) Yes, the day of the week appears to be associated with the nature of the complaint. The category percentages are not consistent on different days. Forexample, the percentage of complaints about delivery is much greater on Fridays.
C) Yes, the day of the week appears to be associated with the nature of the complaint. The categories all have roughly the same percentage across different days.
D) No, the day of the week does not appear to be associated with the nature of the complaint. The categories all have roughly the same percentage across different days.

(b) What supplemental information that is not shown by the chart is important to managers in charge of dealing with complaints? A) Some of the categories are too small to see on the chart. They should be combined into an "other" category so that they are represented in the percentages. B) the exact percentage of each type of complaint on a given day is not known, because the chart only shows an estimated value for each percentage. C) Only the percentage of complaints is shown in the chart, so the actual number of complaints in each category is unknown. D) only the four given categories of complaints are shown in the chart, so the other types of complaints are not represented. Problems with Orders 100 80 60 40 20 0 Wed Thur Fri Mon Tue
