Question

The information below applies to problems 19 to 21.

At this point, the analyst determined that if it takes more contacts to reach a customer before a sale is made, the efficiency and profitability of the sales agent will be reduced. One of the managers at Avalon brought up the fact that one reason for lowered overall sales might be the lack of motivation and drive on the part of the sales agents.

In an effort to explore the profitability issue, the company wants to determine if over the past 3 years the average number of contacts required to write a purchase order has increased? What statistical technique would be used?
a.    Regression
b.    Analysis of Variance
c.    Crosstabs
