The audit firm you work for is auditing the 2022 financial statements for a national clothing retailer. As part of the audit, ADA is being used to assess risk associated with accrued wages. Regression-based ADA was developed, and the first four steps of the five-step ADA process have already been completed. The regression was developed using monthly data from 2019, 2020, and 2021. The regression model was validated from a statistics and a business logic point of view.

The results from the regression analysis are summarized in the following visualization, where the blue dots outside the confidence interval represent November and December 2022. The independent variable is monthly number of employees. The dependent variable is payroll payable at the end of the month.

Required
