Answer:

Error = 166.308459

Explanation:

Given that,

Standard deviation (SD) = $600

Sample (n) = 50 persons

Error(E) = ?

For a 95% confidence interval,

Z-value from the z-table is 1.959963985

E=\frac{z\times SD}{\sqrt{n}}

E=\frac{1.959963985\times 600}{\sqrt{50}}

E=\frac{1,175.97839}{7.07106781}

         = 166.308459

Therefore, the margin of error for a 95% confidence interval is 166.308459.

Answer:

4.15%

Explanation:

In order to determine the annual saving we must divide the extra cost of the hybrid by the amount of years it takes to recoup our investment.

annual savings = $4,180 / 11 years = $380 per year

our initial investment = -$4,180

since we are going to use the car during 15 years, then we have 15 positive cash flows of $380

using a financial calculator or excel spreadsheet, the internal rate of return (IRR) on our investment = 4.15%
