1) A. Biased because the population could be uneven. Too many of one ethnicity, too many of one gender, etc.

2) I believe this one is C. because there are not enough people. You need to survey the majority of parents instead of a selected few.

3) There are 80 green marbles per 500, therefore calculate the percentage. $\frac{80}{500}=0.16$ or $16$ percent. Multiply $16$ percent or $0.16$ times 25. It gives you $4$ .

4) This one is a probability thing too. For every 500 batteries, there are 3 that are defective, therefore, $\frac{3}{500}= 0.006$ .

$0.006*12000 = 72$

5) Yet another one. Add up all the nuts and you get $48$ . The chance of getting a cashew from these $48$ is: $\frac{9}{48}=0.1875$ .

Therefore: $0.1875*32=6$
