Working Principle: Stratified Random Sampling
nx = (Nx/N)*n
where:
nx = sample size for stratum x
Nx = population size for stratum x
N = total population size
n = total sample size
Given:
Nx = 100
N = 1000
n = 0.5*(1000) = 500
Required: Probability of Man to be selected
Solution:
nx = (Nx/N)*n
nx = (100/1000)*500 = 50 men
ny = (Nx/N)*n
ny = (100/1000)*500 = 50 women
Probability of Man to be selected = nx/(nx + ny)*100 = 50/(50+50)*100 = 50%
<em>ANSWER: 50%</em>
It’s 42 heheeeee I’m Michel Jackson
Answer:
ok so lets find what percentage 630 is of 3050
630/3050=0.20655737704
so about 20.7%
Hope This Helps!!!
The answer is $3.57 because you must multiply 2.55 by 140 then divide that by 100 to find your answer hope this helps.
