QuestionT4.7 The sales force for a publishing company is constantly on the road trying to sell books. As a result, each salesperson accumulates many travel-related expenses that he or she charges to a company-issued credit card. To prevent fraud, management hires an outside company to audit a sample of these expenses. For each salesperson, the auditor prints out the credit card statements for the entire year, randomly chooses one of the first 20 expenses to examine, and then examines every 20th expense from that point on. Which type of sampling method is the auditor using for each salesperson? a. Convenience sampling b. Simple random sampling c. Stratified random sampling d. Cluster sampling e. Systematic random sampling

Studdy Solution
Compare the characteristics to the definitions of the sampling methods: - **Convenience sampling**: Selecting samples based on ease of access. Not applicable here. - **Simple random sampling**: Every member of the population has an equal chance of being selected. Not applicable here due to the systematic interval. - **Stratified random sampling**: Dividing the population into subgroups and sampling from each. Not applicable here. - **Cluster sampling**: Dividing the population into clusters and randomly selecting entire clusters. Not applicable here. - **Systematic random sampling**: Selecting a random starting point and then selecting every nth item. This matches the described method.
The auditor is using:
Systematic random sampling \text{Systematic random sampling}
