Answer:

The confidence interval is between 2.23 and 3.53

Explanation:

The confidence interval (C) = 99% = 0.99

α = 1 - C = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

The z score of α/2 corresponds to the z score of 0.495 (0.5 - 0.005) which is 2.576

The margin of error (E) is given as:

E=z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} }\\\\where\ n=sample\ size,\sigma=standard\ deviation\\\\Given\ that\ \sigma=1.59,n=40,z_{\frac{\alpha}{2} }=2.576\ hence: \\\\E=2.576*\frac{1.59}{\sqrt{40} } =0.65

The confidence interval = mean ± margin of error = 2.88 ± 0.65 = (2.23, 3.53)

The confidence interval is between 2.23 and 3.53

The Seattle Corporation has an investment opportunity that will yield cash flows of $30,000 per year in Years 1 through 4, $35,0
zlopas [31]

Answer:

4.86 years

Explanation:

Data provided in the question:

Cash flow each year from year 1 to year 4 = $30,000

Cash flow in year 5 through 9 = $35,000

Cash flow in year 10 = $40,000

Initial investment = $150,000

Firm's WACC = 10%

Now,

Accumulated cash flow for 4 years = $30,000 × 4 = $120,000

Accumulated Cash flow for 5 years = $120,000 + $35,000

= $155,000 > amount invested ($150,000)

Thus,

Remaining payback amount required in year 5 = $150,000 - $120,000

= $30,000

Payback period for $30,000 in year 5 = [$30,000 ÷ Annual cash flow]

= $30,000 ÷ $35,000

= 0.86 years

Hence,

Total payback period for this investment is

= 4 years + 0.86 years

= 4.86 years
