\title{
Failures of Air-conditioning Equipment
}
\description{
Proschan (1963) reported on the times between failures of the air-conditioning
equipment in 10 Boeing 720 aircraft. The \code{aircondit} data frame contains
the intervals for the ninth aircraft while \code{aircondit7} contains those for the
seventh aircraft.
Both data frames have just one column. Note that the data have been sorted
into increasing order.
}
\usage{
aircondit
}
\format{
The data frames contain the following column:
\describe{
\item{\code{hours}}{
The time interval in hours between successive failures of the air-conditioning
equipment
}}}
\source{
The data were taken from
Cox, D.R. and Snell, E.J. (1981)
\emph{Applied Statistics: Principles and Examples}. Chapman and Hall.
