Answer:
(i) The population parameter for the above information is;
The average lifespan of males in Ghana is known to be 55 years.
The average lifespan of females in Ghana is known to be 60 years.
The average lifespan of people from the Northern region of Ghana is known to be 58 years.

(ii) The sample statistics for the above information is;
The average lifespan of a Ghanaian is 57 years.
Step-by-step explanation:
We are given that the average lifespan of a Ghanaian is 57 years. The average lifespan of males in Ghana is known to be 55 years while the average lifespan of females in Ghana is known to be 60 years.
The average lifespan of people from the Northern region of Ghana is known to be 58 years while the average lifespan of people in the East region of Ghana is known to be 54 years.
(i) The population parameter for the above information is;
- The average lifespan of males in Ghana is known to be 55 years. This represents our population parameter because it is written that it is known to be which means from the whole population we came to know that the average lifespan of males in Ghana is known to be 55 years.
- The average lifespan of females in Ghana is known to be 55 years. This also represents our population parameter because it is written that it is known to be which came from the whole population.
- The average lifespan of people from the Northern region of Ghana is known to be 58 years which also represents our population parameter because it is written that it is known to be which came from the whole population.
- The average lifespan of people in the East region of Ghana is known to be 54 years which also represents our population parameter because it is written that it is known to be which came from the whole population.
(ii) As it is given that the average lifespan of a Ghanaian is 57 years. This means that we have taken a sample from the whole population which resembles our population data ad from there we have concluded that the average lifespan of a Ghanaian is 57 years. And in this information, it is not written that we already have known about this lifespan.
