Answer:
Initial capital $700
Interest rate 9%
Period 6 years
Interest paid by year: (700x0.09) =63
Interest paid at the end of the loan: (63x6) = 378
The interval around the mean is 18.55 ≤ μ ≤ 19.45
We follow these steps to arrive at the answer above:
Confidence level : 95%
Confidence Interval Estimate: Sample mean ± t_n-1* (s/√n)
Critical t value at n-1 df (300-1 = 299 d.f) is 1.96793
Substituting values in the formula above we get,
Confidence Interval Estimate = 19± 1.96793 (4/√300)
Confidence Interval Estimate = 19 ± 0.454473966
Answer:
33.33%
