Question

Quizplus · Accepted Answer

All of the given options are true. Phone books only have landline numbers, which means that households with only wireless numbers (which are becoming increasingly common) are not included. Phone books also do not always have accurate information, as households may have moved or changed numbers without updating their information. Additionally, phone books only cover certain geographic areas, so households in non-coverage areas or those who have recently moved to a new area may not be represented in the study.
