In a demographic study, the population and total income of a certain region were estimated from other data, and both estimates had lower and upper limits. At the time of the estimates, was the per capita income for the region greater than $16,500?

(1) The lower limit for the estimate of the population was 330,000 people.

(2) The lower limit for the estimate of the total income was $5,500,000,000. (E)

why not C?

per capita income=total income/ total population;所以只有人口下限和收入上限才能算出最大,reveresely,可以得到income的最小值,这样才可以定16,500是否符合.
