Atown planner is interested in getting some demographic data about the households in the city. the city has four wards with the following numbers of households: ward a has 2,107, ward b has 903, ward c has 1,505, and ward d has 1,499. the budget for the project allows the planner to survey 100 households. she plans to use a stratified sampling method. how many households should be chosen from ward b? enter a whole number.

15

Step-by-step explanation:

Population size= 2107+903+1505+1499

                        = 6014

Calculating the sample of ward B by using the stratified random sampling formula:

Stratified Random Sample, np= ( Np / N ) * n

where

np= pth stratum  sample size

Np= pth stratum  population size

N = population  size

n = sample size

Stratified Sample (ward B) = 100 / 6014 * 903 = 15 !
