Session Unit 2:
8. Statistical Concepts and Market Returns
Example, p.259: Consider a CFA practice exam that was administered to 36 Level I candidates with mean score = 80.
Assuming population SD = 15 (known), construct and interpret a 99% CI for the mean score (note: n > 30).
CI = 73.55 - 86.45
Interpretation?
We are 99% confident that the population mean score lies between 73.55 and 86.45 for candidates from this population.
