Which survey is most likely affected by bias?
o
a survey of teenagers about their favorite colors
survey of students about vacation policies in a school district
a survey of supermarket shoppers about products they would like to see added
a survey of bike riders on whether they wear helmets

(b) survey of students about vacation policies in a school district

Step-by-step explanation:

The survey is said to be bias if each type of unit is not selected in the sample.

(a) Survey of teenagers is not affected by bias because they were surveying about the teenagers and also take survey from teenagers.

(b) Since they are doing the survey of students but take survey from school district, So result will not equally likely as the opinion of student is different from School district. Thus, this survey is affected by bias.

Same criteria is taken for other two options and they are not affected by bias.

Step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
