In Spring 2000 a team measured ping times of Internet servers at various
distances from Raleigh using a software program called NeoTrace. They
actually measured ping times at 4 different times of the day, but since
there was very little difference over time, we have averaged over the
times of day.
A data frame with 12 observations on the following 2 variables.
: distance from Raleigh
: ping response time
