Refrigerator: Refrigerator Energy Consumption
Description
Thirty 18 cubic feet refrigerators were randomly selected
from a company's warehouse. The first fifteen had their motors modified
while the last fifteen were left intact. The energy consumption
(kilowatts) for a 24 hour period for each refrigerator was recorded and
stored in the data frame Refrigerator. The refrigerators
with the design modification are stored in the variable modelA,
and those without the design modification are stored in the variable
modelB.source
