Answer:

67%

Test for 2 Independent means

Explanation:

Given that:

Average Female earning per week in sample = $346.98

Average Male earning per week in sample = $517.70

Female earning in percent of male earning :

(Female earning / male earning) × 100%

(346.98 / 517.70) * 100%

0.6702337 * 100%

67.02%

= 67%

Testing whether or not the difference in weekly earning by males and female can be conducted by testing the difference in sample means of both males and females by taking the two different samples as being independent.

Usually :

Null hypothesis : H0 : m1 - m2 = 0

Alternative hypothesis : H1 : m1 - m2 ≠ 0

You own factory A and factory B. The next cash flow for each factory is expected in 1 year. Factory A has a cost of capital of 3
ziro4ka [17]

Answer: See Explanation

Explanation:

First, we have to calculate the worth of factory A which will be:

= Cash flow / Cost of capital

= $19300 / 3.5%

= $19300 / 0.035

= $551428.57

= $551429

Cost of capital of Factory B = Cash flow / Worth

= $19,900 / $545,000

= 0.0365

= 3.65%

Cost of capital of Factory A = 3.5%

Cost of capital of Factory B = 3.65%

Worth of factory A = $551429

Worth of Factory B = $545,000

Therefore, factory A is more valuable than Factory B and Factory B is more risky than Factory A.

suter [353]

Answer:

Ethics

Ethics also called moral philosophy involves how an individual systemises, defends and recommends the concept of right or wrong.

Summer is facing an ethical decision of either returning the bag or keeping it for herself. Her decision will be based on her definition of right or wrong.

If her moral philosophy is one that does not see theft as something that is wrong, she will decide to keep the bag. If on the other hand she sees keeping the bag that is not her own as wrong she will decide to return it.
