Given that <span>Henry divided the town into eight regions and randomly chose 10 households from each region in order to survey about traffic concerns. This type of sample is called</span> stratified sampling.
Stratified sampling<span> is a type of </span>sampling <span>method where</span><span> the researcher divides the population into separate groups, called strata and then, a probability </span>sample<span> (often a simple random </span>sample<span> ) is drawn from each group.</span>
4/10,5/8,38/100
2 10,8,100
2 5, 4, 50
2 5, 2, 25
5 5, 1, 25
5 1, 1, 5
1, 1, 1
2*2*2*5*5=200
4/10=4*200110
=80
5/8=5*200/8
=125
38/100=38*200/100
=76
76,80,125
The answer is 38%,0.4,5/8
