Determine the situation that best describes a normal distribution. answer choices a. heights of students in a class b. prices of shirts during a sale c. grades of students on an easy test d. cost of houses during inflation

we know that

normal distributions:

a function that represents the distribution of many random variables as a symmetrical bell-shaped graph

It is a very common continuous probability distribution

we know that

heights of students in any class is continuous

because it can be any real numbers

so, option-AAnswer

a.heights of students in a class

Step-by-step explanation:

A normal distribution has following properties:

Normal distributions are symmetric and it has a bell shape graph and and the mean, median, and mode are all equal.

The shirt prices in a sale can be of the same price. The student grades can also be almost same in an easy test and the cost of similar kind of houses will have similar rates.

So, only height of students in a class are not same and they are continuous in nature.

So. the answer is option a.heights of students in a class,

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
