Doug Iceberge, senior- in- charge of the audit of Fisher Industries, has decided to test the following two controls for Fisher€™s revenue process.

1. All sales invoices are supported by proper documentation, that is, a sales order and a shipping document.

2. All sales invoices are mathematically correct. Iceberge has decided to use a non-statistical sampling approach based on the following judgments for each control and has judgmentally decided to use a sample size of 50 sales invoice packets.

After completing the examination of the 50 sample items, Iceberge noted one deviation for control 1 and two deviations for control 2.
