Duplicate refunds, missing receipt numbers, after-hours credits and a correctly limited Benford test make up the AC570 Unit 5 exception testing set for a storage chain. Searches like "ac 570 unit 5 assignment example", "ac570 unit 5 sample" and "ac570 unit 5 example" land here.
What a finished AC570 Unit 5 exception testing set looks like
Four test blocks, a rule-test annex and an exception register, about seven pages. Test one pairs refunds by tenant and amount within five days: 58 pairs among 3,223 refunds, 39 explained as reissues after a voided check, 19 unexplained worth 2,087.13. Test two walks each facility's receipt sequence across 29,985 cash and check receipts: 145 numbers missing, 117 in the void log, 28 unexplained, 21 of them at Facility 22. Test three flags credits outside 8 a.m. to 7 p.m. local time or on Sundays: 1,359 in all, 1,229 posted by the online portal, 130 by staff, 111 of those at Facility 22. Test four runs first digits twice, on two populations. The annex adds 225 over-rent credits lacking approval and 605 without a reason code.
How a AC570 Unit 5 example is structured
Each block opens with its definition: which rows, which field, what counts as an exception and the authority behind that line, whether the office-hours calendar, the refund policy or published conformity ranges. Results follow in a table of expected and observed figures, then a short conclusion drawing a line between what is shown and what is merely suggested. The Benford block is written with particular care. It states the expected share for each leading digit, log base ten of one plus one over the digit, 30.1 percent for ones falling to 4.6 for nines, and explains that the pattern belongs to amounts arising across several orders of magnitude, not to figures set by a rate card or a fee schedule. A closing register lists every flagged item once, naming the test that caught it, where it stands and the facility involved.
Refunds paid twice?
Same tenant, same amount, five-day window. Of 58 pairs, 39 trace to checks voided and reissued; 19, totaling 2,087.13, have no void on file and are listed for recovery.
Gaps in the receipt books
145 missing numbers across 31 sequences, 117 explained by the void log. Of the 28 left, 21 sit at Facility 22, where a missing cash receipt means money nobody recorded.
Hours no office keeps
Local time only, per the Unit 3 conversion. Portal credits are real but automatic; the 130 staff entries are the finding, and 111 come from one facility's evenings.
Where Benford fits and where it cannot
All 15,187 credits of ten dollars or more fail badly, MAD 0.0831, because waivers fixed at 25 and 70 dollars lead with 2 and 7. That result says nothing about honesty.
The free-form amounts
Manual adjustments of ten dollars or more, 2,761 of them, show close conformity at MAD 0.0050, chi-square 6.8 against a critical 15.51. Conformity clears nothing; it simply raises no flag.
Where marks go in AC570 Unit 5
The costliest error in this set is Benford applied to the whole credit file and read as evidence of manipulation, when promotional credits equal a rate card and waivers equal a fee schedule; graders treat that as a misunderstanding of the test itself. The mirror error, reading close conformity in the manual adjustments as proof they are clean, costs judgment points too. After-hours counts built on unconverted stamps, or left inflated by portal activity, overstate the timing finding many times over. Duplicate searches that never consult the void log produce a list of honest reissues. Gap tests reported as a bare count, without sizing or the void log beside them, draw interpretation deductions. A test missing the source of its rule draws a method comment in most sections.

AC570 Unit 5 questions, answered
When is Benford's test appropriate?
When amounts arise naturally from many transactions, span several orders of magnitude and are not assigned, capped or set by a schedule. Invoice totals and free-form adjustments usually qualify; rents, fixed fees and check numbers do not. The AC570 sample runs the test on both kinds so the difference is visible, and it excludes amounts under ten dollars, following common practice for first-digit work.
Why report the mean absolute deviation instead of only chi-square?
Because chi-square grows with sample size, so across thousands of amounts it rejects conformity over trivial gaps. The mean absolute deviation averages the gap between observed and expected shares across the nine digits and is read against published ranges: below 0.006 close conformity, up to 0.012 acceptable, up to 0.015 marginal, above that nonconformity. The sample reports both and explains which governs.
What makes an after-hours test fair?
Local time, a stated calendar and a split between people and systems. The sample converts every stamp to the facility's zone, uses each office's posted hours with Sundays closed, and separates the online portal, which posts around the clock by design. Only staff entries outside those hours count as exceptions, which is why 1,359 flags shrink to 130 worth reviewing.
