Answer:
The answer is B. The sample was biased because the survey was only given to a select group (the males). An unbiased sample would be a large group of random people (all genders included).
Answer:
(3, 5, 2)
Step-by-step explanation:
Many authors interpret the triangle inequality to mean the sum of the two short sides must <em>exceed</em> the length of the long side. For side measures 2, 3, 5, the sum of the two short sides is <em>exactly equal</em> to the long side, in violation of the triangle inequality. Hence (3, 5, 2) is not a triangle.

<em>Comment on the triangle inequality</em>
Other authors allow the "or equal to" case, meaning sides of lengths 2, 3, 5 will be considered to be a triangle because 2+3=5. This interpretation of the triangle inequality will result in <em>no solution</em> to your question.
A (3, 5, 2) "triangle" will look like a line segment of length 5. It will have an area of zero.
