1 answer
The data does not support the manufacturer's claim because the slope of the trend line is not approximately two fifths. The slope of the trend line represents the cooling rate, and if it is not close to the claimed rate of two fifths degree per minute, then the manufacturer's claim is not supported. Further analysis of the data may be needed to determine the actual cooling rate of the freezer.
