Bode. Run the frequency-domain analysis to see a plot of the gain of the amplifier. As-is, it's about +38dB in the passband. That's a voltage gain of 10^ (38/20) = 79. Notice that our hand calculations indicated a gain of about 88, so that's pretty close! Now remove CE, and re-run the Bode analysis.
