Sample sizes and working paper

See here re your Q(2) https://opentuition.com/topic/reviewing-of-working-papers

Re your first Q - I don't recognise it - if it was from a relevant source (ACCA exam, approved content or OpenTuition) it should have an answer justification. I suggest that 4 cannot be true because the manager cannot conclude on the balance based on a review of only half the necessary work having been done.

You're welcome!
