An insurance company checks police records on 593 accidents selected at random and notes that teenagers were at the wheel in 90 of them. Complete parts a) through d).
a) Construct the 95% confidence interval for the percentage of all auto accidents that involve teenage drivers.
95% CI = (%, 1%
(Round to one decimal place as needed.)
b) Explain what your interval means.
A. We are 95% confident that the percent of accidents involving teenagers is 15.2%.
B. We are 95% confident that a randomly sampled accident would involve a teenager a percent of the time that falls inside the confidence interval limits.
C. We are 95% confident that the true percentage of accidents involving teenagers falls inside the confidence interval limits.

the answer is c. 23/3

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.
