Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects <em>fail to respond during a survey</em>. Hence, a likely scenario is ; <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em>.</em><em> </em>
- Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.
- If 200 surveys were returned, then 300 of the sample participants did not respond. Which means <em>60% of the sample are non-responsive</em>.
Therefore, a scenario where <em>surveys were mailed to 500 people, and 200 of the surveys were completed and </em><em>returned</em><em> </em>exemplifies a non - response bias.

Step-by-step explanation:
x= centesimal angle (100 degrees in a
right angle)
y= sexagesimal angle (90 degrees in a
right angle)
=
x - y = 15
xx90/100 = y
xx9/10 = y
X - XX9/10 = 15
10x/10 - 9x/10 = 15
=
X/10 = 15
x= 150
y = 150x9/10 = 15x9 = 135
=
using centesimal system:
the sum of all external angles in a
polygon is 400 degrees (a full circle).
one external angle is the complement
of one internal angle to 200 degrees =
200-150=50 degrees.
to find the number of sides of the
polygon we need to find the number of
angles or corners. and that is how many
external angles fit into the full circle.
n = 400/50 = 8
=
the polygon has 8 sides
