Answer:
Scarce resources.
Explanation:
A major reason for studying Economics is to gain an understanding of how a nation can best choose to use its scarce resources and how we must make rational decisions in order to move toward a higher standard of living for all. Some of these scarce resources include money, time, land, labor, capital and entrepreneurship. If these resources are not well managed, it usually results in an economic downturn, recession and inflation which are typically a negative factor for good standards of living for the people living in the particular country.
Hence, a proper allocation of scarce resources would improve the standards of living in a country.
Answer:
Utility
Explanation:
Utility is an economic term used to represent satisfaction or happiness. Marginal utility is the incremental increase in utility that results from consumption of one additional unit.
Answer:
B. The portfolio expected rate of return must be the same for each economic state.
Explanation:
Variance formula = sum of (probability x (r - mean)^2)
r= expected return
if the expected return would be same for each economic state then the mean would equal to expected return which ultimately will give variance zero ( as r-mean would be 0).
Hence the correct option is B. The portfolio expected rate of return must be the same for each economic state.
Answer:
The major faults of measurement are:
- Coverage
- Measurement
- Sampling and
- Response
Explanation:
During business research, the data collected during the survey can become very unusable due to errors arising from the factors listed above.
The problem of coverage arises when for instance an electronic survey is used to collect data from a sample population where 69% for instance, do not have access to a mobile phone or a computer.
Measurement problems during a survey speak to the ability to properly design a questionnaire in such a way that it elicits the right kinds of responses. This means asking the right questions so that the responses or answers are accurate. The irony of measurement error is that one's survey is useless if they got the questionnaire design wrong, regardless of whether or not the response rate was very high.
After administering a survey and there is little or no response, one is said to have an error in response rate. A low response rate increases the error margin of the survey as well as it's unreliability.
Sampling errors are said to occur when the sample size is too small or statistically homogenous such that it does not accurately represent the entire population. When this happens it is termed <em>sample frame error.</em>
Another error can occur when the researcher includes the wrong population or excludes the right population. This is called <em>Error in Population Specification. </em>
