Answer:
C
Explanation:
A farmer would want to look at the economic status of the US because his goal is to sell as much wheat as possible and make the most profit. If he pays no attention to the economy and there's a recession but he still sells his wheat at the normal price, people whose stocks are going down and who are losing money will be unable to, and unwilling to, pay the price. Thus, the farmer must inspect the changing economic statuses of the US to determine the best and most effective way to market out his wheat to the public.
Changes in US racial patterns have no impact on the marketing of the farmer's wheat, so A is incorrect.
The number of births per year is also irrelevant, as is the general population growth numbers because these do not affect the way the farmer will market his crops, so B and D are incorrect.
Hope this helps!
Complete Question:
A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=2.9 and s=3.6. Which statement must be true?
z376 is within 1 standard deviation of the mean.
z37 is between 1 and 2 standard deviations of the mean.
z37 is between 2 and 3 standard deviations of the mean.
z37 is more than 3 standard deviations of the mean.
Answer:
z37 is between 2 and 3 standard deviations of the mean.
Explanation:
Standard deviation is a way of measuring of how much the value sample varies or disperses. A low standard deviation means that the values are near the mean value of the set, whereas a high standard deviation implies that the values are distributed over a wider range.
In reasonably average data sets, the values reflect about 68 per cent of the sample within 1 standard deviation from the mean; about 95 per cent in 2 standard deviations; and about 99.7 per cent within 3 standardized deviations.

Explanation:
The college student loan burden is second only to mortgages in consumer debt In the United States. The government estimates that some 41 million students together owe more than $1.2 trillion. In North Carolina, what is the relationship between student loan debt and the tuition/fees that the students pay? After obtaining data for 14 four-year universities in the State University System of North Carolina (data for Elizabeth City State University and Winston Salem State University were not available), suppose we assume a simple linear modelyi= β0+ β1xi+ εito describe this relationship, where xi is the academic year tuition/fees at school In i
and yi is the average student loan debt of graduates of school i, i = 1, ..., 14. Shown below are summary statistics for the 14 schools.

Answer: 45%
Explanation:
Standard deviation for the portfolio will be a weighted average of the standard deviations of the individual assets.
Risky asset has standard deviation of 20%. Assume the weight is x.
Treasury bills have a standard deviation of 0 as they have no risk. Assume their weight is y.
Target Standard deviation is 9%.
Formula would be:
9% = (x * 20%) + (y * 0%)
20%x = 9%
x = 9% / 20%
x = 45%
