Answer:
The standard deviation of 75 dollars
Explanation:
Standard deviation, S.D.= 75 dollars; Mean, M= 225 dollars; Mean deviation, D= ?
S.D. = √ D² - M
∴ 75 = √ D² - 225
D² = 75² - 225 = 5625 + 225 = 5950
∴ D = √5950 = 24.4 dollars
From the above, it shows that, the standard deviation of 75 dollars contains the middle 95 percent of hourly sales.
Answer:
The answer is: C) The money spent on health care in the United States is not being used effectively.
Explanation:
American citizens spend twice as much as British citizens on health care per year. Even if certain diseases are more common in the US than in Britain, the overall cost of health care is too expensive in the US (100% difference) to be explained by a greater prevalence of just one or two diseases.
The only possible explanation is that the American health care system is not as efficient as the British health care system, therefore health care is more expensive.
<span>Economists would describe Jeff as a user of a public good. Jeff would be considered this because he is consuming something, but this consumption does not reduce the availability of the thing being consumed for others. Jeff is using the cable service, but this does not prevent anyone else from receiving and watching a cable service.</span>
Since he is planning on an annual inflation rate of 2%., the statement that explains the interest rates relating to the CD is nominal interest rate is 3% while the real interest rate is 1%.
A real interest rate refers to the nominal rate which is adjusted for inflation.
- We are given that Interest (nominal rate) is 3% and planned Inflation rate = 2%
- Real interest rate = 1% (Nominal rate - inflation rate)
Hence, the statement that explains the interest rates relating to the CD is nominal interest rate is 3% while the real interest rate is 1%.
Therefore, the Option B is correct.
