The coeffi cient of absorption (COA) for a clay brick is the ratio of the amount of cold water to the amount of boiling water that the brick will absorb. The output below from JMP shows a regression analysis predicting COA from the pore volume (in cm3/g) of 7 bricks. Some portions of the output have been omitted. What is the value of beta with hat on top subscript 0, the estimated intercept. Round your answer to four decimal places.
