Do we have to memorize things such as: 95% confidence = +/- 1.96 standard deviations? Thanks for the response.
Yes you do, you need to know the 90,95 and 99% levels, from what I can recall. One and Two tailed as well!
What about for Student’s t-distribution tables?
You get the tables; as was stated above you need to know the “big three”, 90, 95, and 99.
