Step 1: Using a straightedge, draw a line segment. Draw endpoints and label them P and Q.
Step 2:
Draw a new point that is not on PQ¯¯¯¯¯¯¯¯ and label the point N.
Step 3:
Use a compass to match the distance of PQ¯¯¯¯¯¯¯¯. Do not change the compass setting.

Step 4:
Keep the compass setting from Step 3 and place the needle of your compass on point N and draw an arc (part of a circle).

Step 5:
Draw a point on the arc and label the point M.
Step 6:
Using a straightedge, draw a segment that connects N to M.
Step 7:
Using a ruler, measure PQ¯¯¯¯¯¯¯¯ and MN¯¯¯¯¯¯¯¯¯¯. Write those measures on your construction.

Verify that the distance of each segment has the same measure: PQ=MN.

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
