Demographic study

by alex.gellatly » Tue Jul 17, 2012 8:02 pm
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 total income was $5,500,000.

To find whether the per capita income for the region is greater than $16,500, we need to find
The minimum per capita income = lower limit for the estimate of total income/upper limit for the estimates of the population


Statement 1:INSUFFICIENT
no information about the lower limit for the estimate of total income

statement 2:INSUFFICIENT
no information about the upper limit for the estimates of the population

combining both the statements
no information about the upper limit for the estimates of the population
