Chapter 12.5, Problem 4STP

For Exercises 1-6, choose the correct letter.

A town wants to know the number of cell phones in each household. The town divides the population up by neighborhood and surveys a random number of households in each. What type of survey is this?

F. biased

G. random

H. systematic

I. stratified

Expert Solution & Answer
Check Mark
To determine

Find the type of survey.

Answer to Problem 4STP

I

Explanation of Solution

Given:

A town wants to know the number of cell phones in each household.The town divides the population up by neighbourhood and surveys a random number of households in each.
