Which ones do we have to memorize? I assumed it was 1 sided, (1.28,1.65,2.33 for 90,95,99 respectively) and 2 sided (1.65,1.96,2.58 for the same)? Are there any others? Will we be given tables?
They usually ask questions related to the level of confidence you listed above for t or z distributions. Otherwise, they provide extracts from tables.
