Machines at a bottling plant are set to fill bottles to 12 ounces. The quality control officer at the plant periodically tests t
he machines to be sure that the bottles are filled to an appropriate amount. The null hypothesis of the test is that the mean is at least 12 ounces. The alternative hypothesis is that the mean is less than 12 ounces. What are the possible types of errors that could be made from this test?

Answer:
D. 3.66%
Explanation:
For computing the after tax cost of debt we need to apply the RATE formula i.e to be shown in the attachment
Given that,
Present value = $2,120
Future value or Face value = $2,000
PMT = $2,000 × 6.6% ÷ 2 = $66.60
NPER = 18 years × 2 = 36 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after solving this,
1. The pretax cost of debt is 3.05% × 2 % = 6.10%
2. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 6.10% × ( 1 - 0.40)
= 3.66%
