Two computer users were discussing tablet computers. A higher proportion of people ages 16 to 29 use tablets than the proportion of people age 30 and older. The table below details the number of tablet owners for each age group. Test at the 1% level of significance. (For subscripts let 1 = 16-29 year old users, and 2 = 30 years old and older users.)

State the null and alternative hypothesis:

In words, state what your random variable P'₁ − P'₂ represents:

State the distribution to use for the test. (Round your answers to four decimal places.)

What is the test statistic?

What is the p-value? what does it mean

Sketch a picture of this situation

Indicate the correct decision

Explain how you determined which distribution to use.

Question 1:Fact I:Consider the following setup that follows the standard Solow model in Country A.There are N consumers,each
endowed with one unit of available time.Consumers do not value leisure and they divide output between consumption and savings
according to the following rule:a fraction s of output is saved,and the rest is consumed.There is a representative firm that has a Cobb-
Douglas production technology of the form Y=zF(K,N),where K denotes capital,N denotes Labour,z is(Total Factor Productivity
（TFP).Initially country A had 100 units of Capital,144 units of labour and population growth rate was 0.01.Suppose you are given
the fact that in this economy depreciation d is 0.09 and at steady state,the output per-capita could be expressed as y*=(k*)05.Now,
consider the unfortunate situation where a disease took several lives,reducing the number of labour force equal to 81 units.
1.1 Describe and explain changes/effect of this disease on country A's per-capita output,and per capita capital in the steady
state,comparing these with the initial steady state that was prevailing before the disaster.(Note:you are supposed to
describe and explain changes in detail,following Solow Model.The numbers are provided to give you more details
about the economy,but you are not required to provide mathematical derivations/numbers for this question).
1.2 If you were illustrating the old and new steady state in a diagram,with per-capita capital in x-axis,describe how your
graph would change before and after the disease.Would you expect the growth rate of output per worker in country
A smaller or greater than it was before the disease?

George de la Tour's Saint Joseph the Carpenter painting: Address the following questions, and explain how you arrived at your answers:

1. Which methods of color and light do la Tour use in the work?

2. How is color and light used to determine compositional emphasis or a focal point?

3. Thinking back to Chapter 2 and the section on line and shape, does la Tour use line and/or shape to create emphasis?

4. Does la Tour's use of color and light help convey a message? What is it? Are these elements related to any symbolism in the image?

1) List the four most important hardware components of a computer (in your opinion or based on a source) and detail what their function is. You can use the slides or conduct your own research. Make sure you cite any external sources appropriately. (Approximately 300 words)

2) In class, we talked about different protocols that are used to transfer data across networks. Pick two protocols and detail how they work, then compare and contrast them. Finally, discuss when each protocol would be more useful (e.g., protocol x is more useful that protocol y when transferring large quantities of information). As usual cite any sources you used to lookup the protocols. (Approximately 400 words)

3) The last question is an open ended discussion question: what are the environmental impacts of creating and developing technology in such a fast pace? How can we mitigate it? You can include your own answer or do some research to answer these questions in more depth (Approximately 300 words)

SOCIAL SECURITY OLD AGE INSURANCE IS THE TOPIC

These are the topics to include:

• Part 1: Use positive economics* to analyze the current situation.

• Part 2: Use normative economics** to analyze the current situation. Do you believe the current situation comes down too much on the side of equity or efficiency? Explain.

• Part 3: Come up with a plan for how you believe the situation could be improved. In this section, you will need to come up with at least one (1) specific policy that the government could implement and how you believe this policy will change the situation both domestically and potentially globally.
  *Positive economics is an analysis of facts; what is.

**Normative economics uses economics to make value judgments about the situation.

Explain in detail the Frank-Starling law of the heart. Be sure to define what it is, and describe how it operates (the mechanism). Explain why it is an important way that cardiac output is regulated. Demonstrate your understanding by describing a particular scenario when it would operate and its significance.

Question 3 [7]
Identify and briefly describe seven (7) policy measures that have been proposed and
instituted to address structural unemployment in South Africa.

Question 4 [18]
In the aftermath of Covid-19, a further decrease in government expenditure can be expected
to be announced by the minister. Discuss in detail the internal and external effects of such
an expected decrease in government expenditure. In your answer, address the expected
primary effect in terms of the real side of the economy, as well as other monetary effects
expected, such as effects in the money market, the expected foreign reserves adjustment
process and the expected exchange rate adjustment process, all as part of the secondary

Question 6 [17]
Using diagrams, illustrate and explain in detail what the basic idea of macroequilibrium is.
Tip: Use two diagrams next to each other.

Question 7 [14]
7.1. Indicate which variables that are relevant to the IS and LM curves will help you
remember which curve is which. (4)
7.2. Draw a diagram of a typical IS-LM model and on the diagram indicate the changes in
all the variables should there be an increase in aggregate expenditure causing a shift
of the IS curve to the right (indicate the shift in the IS curve on your diagram). Label
the axes properly. (5)
7.3. Interpret the diagram that you have drawn for 7.2 and briefly explain your
understanding of what the IS-LM model is reflecting in terms of macroeconomics. (5)

Question 8 [15]
8.1. Define the balance of payments (BoP) of a country. Also explain what the current
account of the BoP records and what the financial account of the BoP reflects. (6)
8.2. Which important factors determine the volume of imports in a country such as South
Africa? (4)
8.3. What does the term “net exports” mean and what is a direct component of net exports
in real terms? (2)
8.4. Explain in detail what capital flows reflect in terms of the BoP analysis and what flows
are included.

explain the 2019-2020 Economy of the US and/or World. Discuss issues such as: What is currently occuring? How is it affecting people and businesses. How is it affecting the local, regional, national, and world markets. How are local and state gov'ts being affected and what are they doing? What is the federal gov't doing or proposing to do to help the situation? What do you think of the federal gov't proposals and/or actions? What would you suggest doing? What has caused this recession (what the experts say and/or what do you think)? How is the recession affecting you and your family personally? What do you think the future will be like? How about the stock market? What are your thoughts about the auto industry and the auto bailout? What are your thoughts about the financial/banking bailouts? The volatility of the stock market?

Please answer by type words, do not hand writing and pictures

1. Does your state have an individual income tax? If so, how closely does it conform to the federal tax? Can one deduct the federal tax in computing the state income tax? List some specific ways that the federal and state tax bases differ. What problems, if any, do these differences create in computing your taxes? What additional issues have been created in as a result of Federal Tax reform in 2017. (10 points)

2. What is the rate structure of your state income tax? Are the rates progressive, and if so, how does that progressivity compare to the federal income tax rate structure? (5 points)

3. The two most important state taxes are income and general sales taxes, although states also make substantial use of excise taxes, direct business taxes (usually a corporate income tax), and others. List and discuss briefly four factors that might influence a state in choosing between an income and general sales tax. What is the relative reliance in your state on these two taxes? If the relative reliance in your state is different than average, speculate about why that might be so. (10 points)
