Following enlisted are the answers for the above mentioned question.
Explanation:
1. Population pyramids is graphical representation of data which enables oneself to distinguish and have a clear picture in minds about the ratio of population densities keeping any one parameter as constant. Population pyramids could be used to analyze data in many different scales on the basis of gender,age groups, race etc. Examples-having a record of no. of individuals in different age groups in India.
2. Generally, there are 3 types of population pyramid on the basis of shapes of the pyramid. Those are;
- Expansive
- Constrictive
- Stable
Siting an example of age-sex pyramids,
In case of the Expansive, population pyramids show that the populations that have a larger number of persons in young age groups. The shape obtained hence is usually with high fertility rates with lower death rates
Then comes, Constrictive population pyramids. These are named so since they are constricted at the bottom. They undue a low percent of young people as compared with other age groups. These type of pyramids show decreasing birth rates.
And at last, Stationary also called as stable population pyramids are the ones which depicts almost equal proportion of the population in each of the all age groups. There is not a decrease or increase in population; it is stable.

A binomial random variable is one based on a given number of specified
outcomes from a given number of trials.
- The choice that is a binomial random variable is Choice B; <u>Amelia rolls 5 fair dice. Let </u><u><em>D</em></u><u> equals the number of dice that show a value greater than 3</u>.
Reasons:
A binomial random variable is the variable that represents the number of
times a specified event occurs in a given number of trials.
From the above definition of the binomial random variable, we have;
The binomial random variable is the option;
<u>Choice B Amelia rolls 5 fair dice. Let </u><u><em>D</em></u><u> equals the number of dice that show </u>
<u>a value greater than 3</u>, because, of the following;
- The number of trials are specified as 5
- The variable which is the event that is being observed, is specified as the number of times when the dice show values greater than 3.
<em>Choice A is a geometric random variable</em>
<em>Choice C is a random variable</em>
