In a simple way it is an AMPLITUDE question. You can calculate amplitude by formula which is Sin Amp=Sin Dec ÷ Cos Lat. And to covert Amp to 360° notation. And compare true bearing with compass bearing and calculate compass error.
Yes exactly, however the OOW yacht syllabus requires you to use Norries amplitude table, now known as the true Azimuth at rising or setting since 2017 version of Norries. You could very quickly confirm via a calculator..
