A reporter for Humber Report on Business obtains a numbered listing of the 1000 Canadian companies with the highest stock market values, uses Excel to generate 5 random numbers between 1 and 1000 (namely: 367, 80, 411, 569, 764), and then interviews the chief executive officers of companies corresponding to these numbers. This type of sampling is called:

• Cluster sampling
• Convenience sampling
• Stratified sampling
• Simple Random sampling
• Systematic sampling
