To compare power consumption by a newly developed low-power USB device under three test run conditions and record the data transmission rate at the same time, a computer engineer obtained the following results, where the power consumption, \(x\), is in Watts, and the data transmission rate, \(y\), is in Gbps.

Perform an analysis of covariance, using the level of significance \(\alpha=0.05\). Also, estimate the value of the regression coefficient.
