(Objectives 15-6, 15-7) The sampling data sheet below is missing selected information for six attributes involving tests of transactions for the sales and collection cycle.

Attributes		Planned Audit				Actual Results
Attributes	EPER	TER	ARO	Initial Sample Size	Sample Size	Number of Exceptions	CUER
Attribute 1	0%	6%	5%	49	50	1	––
Attribute 2	0.50%	5%	10%	––	80	0	2.9%
Attribute 3	1%	––	10%	55	55	1	6.9%
Attribute 4	1%	6%	5%	78	80	––	5.8%
Attribute 5	0%	4%	––	74	80	0	3.7%
Attribute 6	0.50%	6%	10%	64	––	2	7.5%

a. Use Table 15-8 (p. 502) and Table 15-9 (p. 503) to complete the missing information for each attribute.
b. For which attributes are the sample results unacceptable?
c. Compare attributes 1 and 3. Why does attribute 1 have the smaller sample size?
d. Compare attributes 2 and 5. Why is CUER higher for attribute 5?
