R Dataset / Package Stat2Data / AutoPollution
A dataset with 36 observations on the following 4 variables.
||Noise level (decibels)|
|| Vehicle size:
|| Side of vehicle: code1=right or
In a 1973 testimony before the Air and Water Pollution Subcommittee of the Senate Public Works Committee, John McKinley, President of Texaco discussed a new filter that had been developed to reduce pollution. Questions were raised about the effects of this filter on other measures of vehicle performance. The data set AutoPollution gives the results of an experiment on 36 different cars. The cars were randomly assigned to get either this new filter or a standard filter and the noise level for each car was measured.
