Exam 22: Probability-Proportion-To-Size Sampling

In a probability-proportional-to-size sample with a sampling interval of $10,000,an auditor discovered that a selected account with a book value of $6,000 had an audited value of $4,000.The projected misstatement is:

Probability-proportional-to-size sampling is especially efficient for populations with high misstatement rates.

Which of the following factors would indicate that probability-proportional-to-size sampling should be used rather than other statistical sampling techniques?

In a probability-proportional-to-size sample,increasing the tolerable misstatement has what effect on sample size,when all other factors are held constant?
