Answer:
<h2>Biased.</h2>
Step-by-step explanation:
The research is aimed to find if students would choose engineering as their profession.
So, according to the problem, the researcher chose the same number of male students and female students. In that case, the research would be biased. If the researcher chooses the same number of boys and girls, one group will be overrepresented, because in a school, there aren't the same number of male students and females students, that would be a perfect case which doesn't happen in real life.
So, the equivalence of the sample will bias the study, because it would misrepresented the real situation.
Therefore, the sample is biased.
-2.1-6x=1.5 add 2.1 to both sides
-6x=3.6 now divide both sides by -6
X= -.6
