Detailed Explanations
The Attest Function Process
The attest function involves several key steps:
- Planning the Audit: Understanding the entity, assessing risks, and determining the audit approach.

Mathematical Models/Formulas
In the context of the attest function, quantitative methods such as statistical sampling and analytical procedures are often used:
- Sampling Formula:
$$ n = \frac{NZ^2 P(1-P)}{E^2(N-1)+Z^2P(1-P)} $$
- Where:
- \( n \) = sample size
- \( N \) = population size
- \( Z \) = Z-score (confidence level)
- \( P \) = expected error rate
- \( E \) = precision (tolerable error)
