Which statement is true of an appropriate sample of a population?
a sample must be a group of people who are the target of the survey question.
a sample should have different characteristics than the population.
a sample must be very small.
a sample should include only boys or only girls.

The correct option is 1.

The set of all observations is known as populate set.

A sample is a small subset of population set that is the representative of the entire population. The sample must have sufficient size and it should include all population.

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
