An insurance company wishes to obtain customers' views on their satisfaction with the service they have received. The company decides to survey callers who telephone its call-center, to obtain their views. Explain how you would use systematic sampling to select a sample of 100 callers over a six-day period from Monday to Saturday if you know that the approximate number of calls is 400 each day. Give two reasons why your method may be preferable to simple random sampling.
