Question 4: Substantive Procedures and Audit
Documentation
After the end of the financial year, Jane Owen performed
transaction tests of the inventory purchases and cash disbursement.
She summarised the audit procedures she performed in the following
workpaper (reference N-2). To ensure audit quality, BDC has a
review policy which helps to ensure that each audit document
provides a clear and complete indication of the procedures that
were performed and that adequate evidence has been collected. For
this audit, you must...

Data
For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1,
7.0, 0.5, 3.9, 2.1, 4.1, 6.5
In Tasks 1-8 you are asked to conduct some computations
regarding this data. The computation should be carried out
manually. All the steps that go into the computation should be
presented and explained. (You may use R in order to verify your
computation, but not as a substitute for conducting the manual
computations.)
