An automotive engineer subjects a large number of brake pads to a stress test and measures the wear on each. The values obtained are \(\bar{X}=7.4 \mathrm{~mm}\) and \(\sigma_{\bar{X}}=0.2 \mathrm{~mm}\). Use this information to find the \(P\)-value for testing \(H_{0}: \mu=7.0\) versus \(H_{1}: \mu eq 7.0\).
