Estimating Nigeria's Population

Requirements Clarification & Assessment

1. Understanding the Question

   • The task is to estimate Nigeria's current population and provide a 95% confidence interval for this estimate.
   • A confidence interval is a range of values that is likely to contain the population parameter with a certain level of confidence (95% in this case).

2. What is Needed

   • Data Sources: Reliable data sources or estimates for Nigeria's population.
   • Statistical Methodology: Understanding of how to construct a confidence interval, which typically requires sample data, a known distribution, or an estimate of variability.

3. Challenges

   • Data Availability: Nigeria's last official census was in 2006, and population figures since then are estimates.
   • Methodology: Constructing a confidence interval for a population size is unconventional without sample data.

4. Clarifications Needed

   • What assumptions can be made about the data collection or estimation process?
   • Is there access to recent demographic data from reputable organizations like the UN or World Bank?
   • What is the expected level of precision for the confidence interval?
