Goshia [24]

Answer:

The correct answer is

d. Sampling Interval = Population size ÷ Sample size.

Step-by-step explanation:

According to Johnstone et al., (2014) "Once the auditor has determined the appropriate sample size, a sampling interval is calculated by dividing the population size by the sample size."

Thus,

Sampling Interval = Population size ÷ Sample size.
