Quizplus · Accepted Answer

The estimation of the population average family expenditure on food based on the sample average expenditure of 1,000 families requires inferential statistics as it involves making conclusions about a population based on a sample. The sample average expenditure is a statistic, not a parameter, as it is calculated from the data collected from the sample, not the entire population. Descriptive statistics would involve simply summarizing the data from the 1,000 families without making inferences about the population as a whole.
