Standard Error or Not?

CFA Level I
#1

When do you use the Standard Error in Confidence intervals vs, just multiplying with Standard Dev? I am confused on this part.

#2

same here

#3

understand what a standard error is, then the rest will follow easily.

#4

knowing that the standard error is a standard deviation of the sample means does not help…

#5

Could you give an example question where they use the Stdev and not the StError?

#6

there was a question on mock 1…forgot which, but it was somewhere early in the quant section. they gave mean and std dev but not the n, and asked for the confidence interval
