Confidence Intervals

CFA Level I
#1

Hey guys,

Does anyone know if there will be Z or T tables to lookup the respective statistic during the exam? Should I only worry about memorizing the most common such as at 90%, 95% and 99% intervals?

I only ask because the formulas that include the T-statistic require I use the table in the Schweser notes. If there are no tables on the exam do I even need to waste my time memorizing the formulas that require the T-statistic?

Thanks for any advice

z table - memorize the 1 sided and 2 sided confidence interval z scores for 95, 99 and 90%. (5%, 1% and 10% confidence).

learn to determine how the t-table is used, and be on the lookout for the snippet of the t-table - that would require you to get the score from there.
