The city council in a suburb of Raleigh is interested in the level of public support for a tax increase to support restoration of nearby parks and waterways. A marketing research firm is hired that then selects a simple random sample of 50 adult residents and contacts each to determine whether the resident would be opposed to the tax increase. Of these respondents, 15 indicate that they would be opposed to the tax increase.
What is the population of interest?

Question

Quizplus · Accepted Answer

The population of interest in this case is all adult residents in the suburb, as they are the ones who would be affected by the tax increase and whose opinions are being sought. The sample of 50 residents contacted is just a subset of this population, and the subset of those who would be opposed to the tax increase is even smaller. The survey results are meant to provide insight into the opinions of the larger population. Finally, the option of all households in the suburb is too broad, as not all households may have adult residents or be impacted by the tax increase in the same way.
