Answer:
A (52,2%, 55,8%)
Step-by-step explanation:
To get the confidence interval, we have to add the margin of error to the point estimator.
The middle of the interval is 54%, and the ME is 1.8%. Don't forget that this means ±1.8%!
54 - 1.8 = 52.2%
54 + 1.8 = 55.8%
So our confidence interval is (52,2%, 55,8%) and the answer is A.

Answer:
$3,799.20
Step-by-step explanation:
We presume your formula is intended to be ...
M = Pm(1 + m)^(na)/((1 + m)^(na) - 1)
where M is the monthly payment, m is the monthly interest rate, n is 12, and a is the number of years.
This formula gives written below:
M = 3500·(.08/12)·(1 + (.08/12))^(12·2)/((1 + (.08/12))^(12·2) -1) ≈ 158.30
The total payback will be the sum of 24 of these payments is written below;
payback = 24×$158.30 = $3,799.20
