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.
Answer:3 hours and 30 minutes
10.5, since 35 is between 30 and 40 ((30+40)/2), the mistakes that correspond with them are 9 and 12, the number in between them is 10.5 (9+12=21, 21/2 is 10.5)
