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.

Format

A data frame with 30 observations on the following 2 variables.

modelA
