A mail-order firm was considering a new software package that provided information on products (availability, history, cost, and so forth). To test the software, the next 17 new employees were randomly assigned to use the old or the new software.
After training, each employee completed a search report on 40 products. Analyze the data, which are in minutes, and write a conclusion about the new software package.
