Questions involving cumulative z table table

JustasS

For questions where we have to look up a probability on the z tables, will this be given to us as supplement during the exam, or will the applicable range be on each question it may pertain to?

As far as I can remember, the applicable range will be given for each question that involves the use of z or t stats.

Beatthecfa is correct. However, you need to memorize values for 2 tail 90% 95% and 99% confidence levels as 1.65, 1.96 and 2.58 . If anything other than these is asked, it will be given with that question.

In June, I don't remember a z table being provided- every question was related to the most common confidence levels listed above by rus1bus. Have these memorized.
