Question
An engineer is studying the effect of cutting speed on the rate of metal removal in a machining operation.
However, the rate of metal removal is also related to the hardness of the test specimen. Five observations are
taken at each cutting speed. The amount of metal removed (y) and the hardness of the specimen (x) are shown
in the following table.
