At a certain insurer, support agents earn the same hourly rate on either system. A telephone agent handles one caller at a time and settles, on average (arithmetic mean), six issues an hour. In a trial, agents randomly assigned to a new text-chat system handled three conversations at once and settled nine issues an hour. The director concludes that moving all support to chat will cut labour cost per settled issue by a third.

Which of the following would be most useful to determine in evaluating the director's conclusion?

AWhether agents who work the text-chat system are paid at the same hourly rate as agents who work the telephone

BWhether the agents chosen for the trial were more experienced than the insurer's telephone agents on average

CWhether an issue settled by chat is as likely as one settled by telephone to need no further contact

DWhether the fee the insurer pays to licence the chat system is larger than the cost of maintaining its telephone lines

EWhether other insurers that have moved their customer support to text chat have reduced their labour costs
