A United Nations report shows the mean family income for Mexican migrants to the US is $27,000 per year. A Farm Labor Organizing Committee sample of 25 Mexican families reveals a mean of $30,000, with a sample standard deviation of $10,000. Use this evidence to determine if the United Nations report is incorrect. Use the .01 level of significance. Begin by Stating the Appropriate Null Hypothesis.

Calculate the relevant test statistic.

Should the null hypothesis be rejected?

Is this evidence that the United Nations report is incorrect? Explain.

Wall Street traders use cause-and-effect relationships to profit from news announcements concerning important economic variables such as the money supply. Economists called "Monetarists" have long argued that the primary long-run cause of inflation is excessive growth in the money stock. On the basis of this theory, Wall Street traders attempt to buy and sell stocks and bonds hoping to be the first to capitalize on news of changes in the money stock.

To assess the evidence of this proposition, we gathered monthly data over the period 1980 through 1990 on the M1 money stock and the consumer price index for the United States. We transformed the data using a logarithmic transformation and estimated the following linear regression model:

%∆ CPI = a + b %∆ Money Stock + e.

Results using OLS on a sample of size 132 are provided below.

What is the relationship between money stock and cpi? Interpret the coefficient for the money stock. Also, what does the constant indicate ?.

Economics studies how society allocates its scarce productive resources (land, labor, capital, and entrepreneurial talent). Prior to beginning work on this discussion, read Chapter 2 in the course text, especially examining Sections 2.2 through 2.4, and respond to the following components:

• Briefly describe the types of economic systems. What is the United States’ economic system and what are the characteristics of this economy?
• What economic role or functions does the U.S. government conduct regularly?
• Why is the U.S. government’s economic role important or unimportant for the U.S. economy? Discuss whether you favor a larger or smaller government role in the economy.

Your initial post should be a minimum of 300 words.

Guided Response: Respond substantively (a minimum of 100 words) to at least two of your classmates’ posts. What is different or similar between your post and your classmates’ posts? What advice could you offer your classmates? Substantive responses use theory, research, and experience or examples to support ideas and advance the class knowledge on the discussion topic.

1. The cash payment by a consumer or employer to an insurance company is called:

A) A co-payment

B)  A deductible

C) A limit

D) A premium

A) Blue Cross-Blue Shield

B) Veterans Affairs

C) Medicare

D) Medicaid

3. The part of Medicare that helps pay for ambulance services is:

A) Part A

B) Part B

C) Part C

D) Part D

4. True or False? An economic unit refers only to individuals.

5. True or False? Both wages and noncash benefits are subject to income tax.

6. True or False? Cost-of-illness results should be used as the sole source for policy recommendations.

7. True or False? Medicare consists of five parts.

8. True or False? Part A is largely financed by a federal payroll tax paid by employers and employees.

9. True or False? Profiling involves collecting comparative data on the treatment patterns of providers.

10. True or False? Vertical integration refers to joining together of buyers and sellers.

Directions: For each question, you need to show each step of the hypothesis test, state your null and alternate hypothesis, identify if you are conducting a two-tailed or a one-tailed hypothesis test, identify the Zcrit and Zobt, graph the normal curve, label the critical value and the test statistic, shade the rejection region, tell whether we reject or retain the null and make a conclusion statement. You also need to calculate Cohen’s d, the probability of committing a type I error and type II error, and the strength of the effect size.

2. The national recidivism rate in the United States at three-years post-release is 67 with a standard deviation of 8. The warden at a local prison introduced a new reentry program aimed at reducing the rate that offenders return to prison. To test whether this new program is effective at reducing the recidivism rate of offenders at this local prison he selects 16 offenders to include in the sample and finds that the sample mean is 64. Use a nondirectional one-sample z test to test to determine the new program has an effect on recidivism.

Alternative-Fueled Vehicles The table shows the numbers (in thousands) of alternative-fueled

vehicles A in use in the United States from 1995 to 2011. (Source: U.S. Energy Information Administration)

(a) Use a graphing utility to plot the data. Let t represent the year, with t = 5 corresponding to 1995. (b) A model for the data is

4615.36t − 8726.7

1 + 15.01t − 0.542t2, 5 ≤ t ≤ 21

where t = 5 corresponds to 1995. Use the model to estimate the numbers of alternative-fueled vehicles in 1996, 2006, and 2011. How do your answers compare to the original data?

(f ) Use the model to predict the numbers of alternative-fueled vehicles in 2016 and 2017

* Need help to understand F . Should I be using a particular formula

If the number employed is 150 million, the prime working-age population is 190 million, and the number unemployed is 10 million, the labor force participation rate is 65%, then the unemployment rate is
  
21.1%
8.2%.
6.3%
5.3%
can not be determined because we do not know what the labor participation rate for the actual working age population is.

In the United States, from the first quarter of 2020 to the second quarter of 2020, assume that real GDP decreases by 2.3%, the unemployment rate rises from 3.6% to 8% and the CPI index goes from 148 to 134. In such an economic scenario,
  
The aggregate demand curve must have shifted leftward, moving down along a short-run aggregate supply curve.
The short-run aggregate supply curve must have shifted leftward, moving up along the aggregate demand curve.
The aggregate demand curve must have shifted rightward, moving up along a short-run aggregate supply curve.
The short-run aggregate supply curve shifts rightward, moving down along the aggregate demand curve.
