An internal auditor wants to select 60 vendor payments from a population of 6,000 so that each payment has an equal chance of selection, and the choice is free from the auditor's bias. Which method fits best?

Random sampling with a random number generator fits best. It gives every payment an equal probability of selection and removes the auditor's personal bias. Haphazard choice, picking only the highest values, or taking one week's payments are judgmental or unrepresentative and cannot support objective conclusions about the whole population.

  4. DSelecting all payments made in the last week

Explanation

Random sampling gives each item an equal chance and removes personal bias, allowing objective conclusions. Haphazard picking is not truly unbiased, top-value selection is a targeted judgmental choice, and last-week selection covers only one period.
