Workstation Comparison

Description

To compare the speed differences between two different brands of workstations (Sun and Digital), the times each brand took to complete complex simulations was recorded. Five complex simulations were selected, and the five selected simulations were run on both workstations. The resulting times in minutes for the five simulations are stored in data frame Sundig.

Usage

Format

A data frame with 5 observations on the following 3 variables:

SUN

time in seconds for a Sun workstation to complete a simulation

DIGITAL

time in seconds for a Digital workstation to complete a simulation

d

difference between Sun and Digital
