Answer:
Stratified random sampling is based on a subdivision of the sample framework into strata with the help of an observable variable that separates them. After forming the strata, each individual is located in one and only one stratum. The sample is established by selecting a certain number of individuals in each stratum, guaranteeing a contribution of each stratum in the information obtained.
The best sampling method, in this case, is Stratified Random.
Step-by-step explanation:
1. Use a straightedge to draw line m and label a point on the line as point F
2. Construct a line perpendicular to line m through point F. Label a point on this line as point G.
3. With the compass open to the desired side length of the square, place the compass point on point F and draw an arc on line m and an arc on FG←→ . Label the points of intersection as points H and K.
4. Without changing the compass width, place the compass point on point H and draw an arc in the interior of ∠HFK.
5. Keeping the same compass width, place the compass on point K and draw an arc in the interior of ∠HFK to intersect the previously drawn arc. Label the point of intersection as point J.
6. Use the straightedge to draw JH¯¯¯¯¯ and JK¯¯¯¯¯.
