Answer: The answer is C
Step-by-step explanation: The median is the statistic that can help draw conclusions relative to half of the data in the sample.
Since the median household income for Cartesian is $50,000, at least half of the households in Cartesian have an income of $50,000 or greater.
Also, since the median household income in Pascalville is $68,000, at least half of the households in Pascallvile have an income of $68,000 or greater.
The generalization, based on this sample, is that at least half of the household incomes in both towns are $50,000 or greater.
