The City of Berrysville intends to purchase a new computer system. After extensive search and comparison, the committee responsible for selecting the new system has narrowed the alternatives to two: Number Cruncher I and Graphic Design III. Both systems were tested for reliability last year by an independent research firm, which provided the following results to the committee:

Number Cruncher I

Number of Breakdowns 36

Mean Number of Breakdowns 11.4

Standard Deviation of 9.8

Graphic Design III

Number of Breakdowns 36

Mean Number of Breakdowns 15.2

Standard Deviation of 4.3
