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 !
