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.

Calculation:

Stratified sampling divides the population into groups called strata. Here it is divided by the characteristic of neighbours .A random sample is then taken from these strata and survey is done.So, the type is Stratified.

So , correct option is I.
