I want to know the answer to the following question:
How much of the Nigerian population has access to clean water?
All the background I'm provided with is that "As of 2014[update], Life expectancy in Nigeria is 52.62 years on average according to CIA, and just over half the population have access to potable water and appropriate sanitation; As of 2010[update], the Infant mortality is 8.4 deaths per 1000 live births.". Is that enough to answer the question?
Answer: yes
