A. By Using Judgement
Column	Planned Audit										Actual Result
	ARACR			TER			EPER				Population  Size		Initial Sample
1	10			6			2				1000		90
2	5			6			2				100000		120
3	5			5			2				6000		140
4	5			6			2				1000		100
5	10			20			8				500		50
6	10			20			2				500		40
7	5			2			0				1000000		180
B. By Using attributes sampling from the appropriate part of table 14-28
Column	Planned Audit												Initial Sample Size
	ARACR		TER			EPER			Population  Size
1	10		6			2			1000				88
2	5		6			2			100000				127
3	5		5			2			6000				181
4	5		6			2			1000				127
5	10		20			8			500				25
6	10		20			2			500				18
7	5		2			0			1000000				149
C.
1. An Increase in ARACR   =									Decrease in Initial Sample Size
2. An Increase in the TER    =									Decrease in Initial Sample Size
3. An Increase in the EPER     =									Increase in Initial Sample Size
4. An Increase in the population size =									Increase in Initial Sample Size
D. Because there are different in ARACR, TER and also there’s a huge different in Population Size
E. ARACR and TER have the greatest effect on the initial sample size and population size has the least effect on the initial sample size
F. Because the exceptions in the actual sample must be evaluated before it is possible to know whether the sample is sufficiently large to achieve the objectives of the test.
