A random survey of people at a mall shows that 22 prefer to take a family trip by car, 18 prefer to travel by plane, and 4 prefer to travel by bus. If 500 people are surveyed, how many should say they prefer to travel by plane?

Respuesta :

Answer:

≈ 205

Step-by-step explanation:

500 x (18 / (22 + 18 + 4)) = 500 x (18 / 44) = 204.5      (≈ 205)

The number of people who prefer to travel by plane is 205 if the random survey of people at a mall shows that 22 prefer to take a family trip by car, 18 prefer to travel by plane.

What is a survey?

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

It is given that:

A random survey of people at a mall shows that 22 prefer to take a family trip by car, 18 prefer to travel by plane, and 4 prefer to travel by bus.

Number of people surveyed = 500

As we know, with simple random sampling, each component of the population has an equal chance of being selected for the sample.

The number of people who prefer to travel by plane can be calculated as follows:

= 500x(18/(22 + 18 + 4))

= 500x(18/44)

= 204.5 ≈ 205

Thus, the number of people who prefer to travel by plane is 205 if the random survey of people at a mall shows that 22 prefer to take a family trip by car, 18 prefer to travel by plane.
