At the end of 2016, the average number of businesses per county in Nebraska was 1,640. The businesses benefit from a state unemployment rate that is historically lower than the nation as a whole. Below is a partial list of counties in Nebraska and the respective number of businesses in operation at the end of 2016:

County # of Businesses
Custer 1,126
Sherman 279
Howard 454
Hall 5,085
Adams 2,794
Buffalo 3,992
Kearney 611
Phelps 1,008
Dawson 1,975

a) Compute and interpret the mean.
b) Compute the range.
c) Compute the variance.
d) Compute the standard deviation.
e) Compute the coefficient of variation for the scores.
f) A sample of counties in Nebraska from 2010 provided a sample mean of 1,331
businesses and a sample standard deviation of 1,151 businesses. What comparisons can
you make between the number of businesses/county in 2016 and 2010 based on these
descriptive statistics?

QUESTION 1 (1,500 pts)

Consider an economy that produces and consumes breads and automobiles. In the following table are data for two different years.

1. Using 2000 as the base year, compute the following statistics for each year: Nominal GDP, real GDP, the implicit price deflator for GDP, and a fixed-weight price index such as the CPI. (Present your results neatly and concisely in a table. You do not need to show your workings)

2. How much did prices rise between 2000 and 2010? Compare the answers given by the Laspeyres and Paasche price indices. Explain the difference.

3. Suppose you are a senator writing a bill to index Social Security and federal pensions. That is, your bill will adjust these benefits to offset changes in the cost of living. Will you use the GDP deflator or the CPI? Why?

Penalty Shots in World Cup Soccer A study1 of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only of the time. The article notes that this is ‘‘slightly worse than random chance.” We use these data as a sample of all World Cup penalty shots ever. Test at a significance level to see whether there is evidence that the percent guessed correctly is less than . The sample size is large enough to use the normal distribution. The standard error from a randomization distribution under the null hypothesis is . 1St.John, A., ‘‘Physics of a World Cup Penalty-Kick Shootout - 2010 World Cup Penalty Kicks,” Popular Mechanics, June 14, 2010.

State the null and alternative hypotheses. Your answer should be an expression composed of symbols: =,≠,<,>,μ,μ1,μ2,p,p1,p2,0.5,ρ,p^,p^1,p^2,r.

Consider two options for controlling global carbon emissions.

Option A. For every year t, every country must meet the same target for emissions per capita, based on their population in 2010. That is the restriction is Ei(t)/Pi ≤ B, where Ei(t) is total carbon emissions from country i in the year t, Pi is their 2010 population, and B is some number that is the same for all countries.

Option B. Each year t, every country must meet the same target for emissions per unit of GDP, based on their GDP (converted to a common currency) in that year. That is the restriction is Ei(t)/GDPi(t) ≤ K, where Ei(t) is total carbon emissions from country i in the year t, GDPi(t) is that country's current GDP in year t, and K is some number that is the same for all countries.

Discuss the strengths and weaknesses of these policies. Which policy do you think is better and why?

Use the table below to answer the following questions.

Which country had the highest level of per capita GDP in 2015?

Artinia

Plazi

Boliv

Ghala

Chi

Which country had the highest rate of growth in per capita GDP from 2010 to 2015?

Ghala

Boliv

Plazi

Does per capita GDP in these countries appear to be converging?

Yes, the countries with the lowest levels of per capita GDP have the highest rates of growth.

Yes, the countries with the highest levels of per capita GDP have the highest rates of growth.

No, the countries with the highest levels of per capita GDP have the lowest rates of growth.

No, the countries with the lowest levels of GDP per capita have the lowest rates of growth.

Analyze new monetary policy actions undertaken by the U.S. government from 2000 - 2010 by describing their intended effects, using macroeconomic principles to explain the actions.

•You should specifically state what the intent of the actions were - for instance, the Fed may have used expansionary policy to help expand the economy in response to a recession. Such policies could have been buying up government bonds - this puts money into the economy since the Fed is buying these bonds from a bank and then the bank can use that money in the economy. This open-market operation increases the money supply.

Then, use our macroeconomic principles and models (like the Supply and Demand of Money model, AD-AS model to show the impact of interest rates on equilibrium GDP, Phillips Curve, etc.) to explain why the action would lead to the outcome desired by the government.

please relate the answer to 2000-2010 and please add a reference, thank you so much!

According to a census​ bureau, 12.5​% of the population in a certain country changed addresses from 2008 to 2009. In​ 2010, 14 out of a random sample of 200 citizens of this country said they changed addresses during the previous year​ (in 2009). Complete parts a through c below. a. Construct a 99​% confidence interval to estimate the actual proportion of people who changed addresses from 2009 to 2010. A 99​% confidence interval to estimate the actual proportion has a lower limit of nothing and an upper limit of nothing. ​(Round to three decimal places as​ needed.) b. What is the margin of error for this​ sample? The margin of error is nothing. ​(Round to three decimal places as​ needed.) c. Is there any evidence that this proportion has changed since 2009 based on this​ sample? Because the confidence interval found in part a ▼ includes does not include the reported proportion from​ 2009, this sample ▼ does not provide provides evidence that this proportion has changed since then.
