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: $0.1875*32=6$

morpeh [17]

Answer: b. 3

Step-by-step explanation:

We know that , the indicator variable is a dummy variable in regression analysis which is used to denote either presence ( by 1 ) or absence ( by 0 ) of a nominal variable that can be responsible for the change in output.

Number of indicator variables = (all levels in the original variable)-1

Here , the given categories as per the location are northeast, northwest, southeast, or southwest.

i.e. all levels in the original variable = 4

Then, the umber of indicator variables we need = 4-1 =3

Hence, we need 3 indicator variables.

Thus , the correct answer is b. 3.
