Including the <u>testing of hypotheses</u>
<h3>
What are Testing Hypotheses?</h3>
In statistics, hypothesis testing is the process by which a population parameter assumption is put to the test. Depending on the type of data used and the goal of the research, the analyst will choose a certain approach.
Utilizing sample data, hypothesis testing is a method used to determine whether a hypothesis is tenable. Such information could originate from a bigger population or a data-generating process. In the following descriptions, "population" will be used to refer to both of these scenarios.
A statistical sample is tested by an analyst during hypothesis testing with the aim of demonstrating the plausibility of the null hypothesis.
By measuring and reviewing a representative sample of the population under study, statistical analysts can evaluate a theory. Every analyst employs a random population sample to test the null hypothesis and the alternative hypothesis.
A null hypothesis may declare, for instance, that the population means the return is equal to zero. The null hypothesis is typically an equality hypothesis for population parameters. A null hypothesis is effectively the opposite of the alternative hypothesis (e.g., the population means the return is not equal to zero). They cannot both be true because they are mutually exclusive.
Therefore, one of these two hypotheses will be true.

Complete Question:
If a firm that repairs both motorcycles and cars is able to do so at a lower cost than a firm that repairs only one or the other, this would be an example of __________.
Group of answer choices
A. economies of scope
B. economies of scale
C. monitoring
D. increasing transactions costs
Answer:
A. economies of scope
Explanation:
If a firm that repairs both motorcycles and cars is able to do so at a lower cost than a firm that does only one or the other, this would be an example of economies of scope.
Economies of scope can be defined as an economic factor which makes proportionate savings possible as well as reducing the cost of production when products are manufactured together instead of manufacturing them individually or separately.
Answer:
$28,533.5
Explanation:
Principal value (PV) = $275,000
Time = 20 years
Rate = 8.25%
Present Value = P ((1-(1+R)^-n) / r)
275,000 = P ((1- (1 + 0.0825)^-20) /.0825)
275,000 x .0825 = P (1-(1/1.0825)^20)
22687.5 = P ((1.0825^20 - 1) / (1.0825 ^20))
22687.50 = P (4.8816 - 1 / 4.8816)
22687.5 = P (3.886 / 4.8816)
22687.5 = p(0.7951)
P = 22687.5 / 0.7951
P = $28533.5
