Answer:
The conditions for creating a confidence interval for the population proportion have been met.
Explanation:
There are the following conditions to build a confidence interval for a population proportion:
Sample of size n from a large population
Individuals chosen independent of one another
At least 15 failures and 15 sucesses in the sample.
In this problem, we have that:
Sample of 100 people
They are chosen at random at the market, so it means that the probability that an individual likes the new design is independent of any other individuals.
82 successes and 18 failures.
So yes, the conditions for creating a confidence interval for the population proportion have been met.
Answer:
A. 2 years
B. 86.96
C. 16.46%
Explanation:
Payback period calculates the amount of time taken to recoup the initial investment made on a project.
The net present value substracts the present value of tax adjusted cash flows from the amount invested in the project.
Using the financial calculator to find the NPV:
Cash flow for year 0 = -500
Cash flow for year 1 = 300
Cash flow for year 2 = 200
Cash flow for year 3 = 150
Interest rate = 6%
NPV = $86.96
Internal rate of return is the discount rate that equates the tax adjusted cash flows from a project to the original amount invested.
Using the financial calculator to find the NPV:
Cash flow for year 0 = -500
Cash flow for year 1 = 300
Cash flow for year 2 = 200
Cash flow for year 3 = 150
Interest rate = 6%
IRR = 16.46%
Answer:
Higher inflation, lower unemployment
Explanation:
There are no answer choices but in general, if there is economic growth, the LRAS curve (vertical) shifts right, and higher economic growth means more people become employed. Relating that to the phillips curve, lower unemployment will move up the curve to higher inflation.
Answer:
<em>Value $ 256,250</em>
<em>rounding against nearest 1,000 dollar: 256,000</em>
<em />
Explanation:
From the gross income we subtract the expenses and vanacy losses.
40,000 gross income - 3,500 vacancy - 16,000 operating expense
20,500 net
<em />
Now, we solve for the present value of a perpetuity given the capitalziation rate of 8%
$ 20,500 / 0.08 = <em>$ 256,250</em>
Answer:
The correct answer is letter "C": produces products that are considered elastic.
Explanation:
Elasticity refers to the sensitivity of a good or service to reflect change in its supply or demand after a change in price. A product's supply is said to be elastic if the changes in the quantity supplied increases and it immediately determines a price in the price.
Thus, if for technological reasons the output of a company increases, considering that the product is elastic, the prices will increases which will provide the organization more revenue. That firm will be more than glad about the technological advance.
