Based on the statistical data obtained from survivors countries in South America through the Population Reference Bureau (2013) and World Bank (2015), please analyze the relationship between Gross National Product (GNP) and infant mortality rates per 1,000 births.

1. What is the r value for the relationship between the data distributions above?

2. What is the proportion of variance accounted for?

3. In your own words but based on the strength and direction of the relationship you calculated, explain the relationship between Gross National Product and infant mortality.

1) Anatomically modern humans first reached North and South America by crossing _____________.

1. Northwest passage

2. Beringia

3. The Pacific

4. The Atlantic

2) According to the multi-regional model of human evolution, humans most likely evolved from

1. whatever species of hominid was found in each region; gene flow kept the populations linked

2. Neandertal populations in Europe and Asia.

3. a single population of Homo heidelbergensis somewhere in East Africa

4. populations of Homo erectus spread all across the old world with gene flow between them

3) How are Mousterian tools different from Acheulean and Oldowan tools?

1. Mousterian tools are larger than Acheulean and Oldowan tools

2. Acheulean and Oldowan tools are unifaced (one-sided) while Mousterian tools are bifaced

3. Mousterian tools were made by anatomically modern humans while Acheulean and Oldowan tools were made by Neandertals

4. Mousterian tools have only been found in North America, while Acheulean and Oldowan tools have only been found in Europe, Asia, and Africa

5. To make a Mousterian tool, one must strike the tool from the stone core

4) Neandertal skulls can be differentiated from Homo sapiens skulls

1. by the larger supraorbital torus of Homo sapiens

2. by the presence of an occipital bun and lack of a chin.

3. by the smaller brains of Neandertals.

4. because only Homo sapiens are found in Europe.

5) The Out-of-Africa Model of human origins:

1. Argues for replacement of existing populations by modern humans

2. Claims that Neandertals did not contribute genetic material to the human lineage

3. All of these

4. Suggests that humans had a single, localized origin

U.S. wars in Iraq and Afghanistan, political unrest in South America, growing U.S. antipathy  in Iran, and civil wars in Africa have driven crude oil prices up several times in the last several years.  Although oil prices fell significantly in 2011, they are expected to rise again as the world economy recovers. Adding to the uncertainty, it is predicted that natural gas prices, which fell in concert with significant new gas field discoveries, will rise as more and more utilities switch from using coal or oil to natural gas.

Suppose you are the manager of a public utility that supplies electricity to a significant portion of your geographic region. You preside over electrical generation facilities that can produce electricity using either natural gas or oil, or some combination of both.

In the past several years, you have been faced with skyrocketing, then plummeting, natural gas prices, and now think you face the possibility of more of the same, coupled with the probability of similar volatility in oil prices.

Having been trained in Managerial Economics, you are familiar with production functions, isoquant and isocost analysis, and other tools of microeconomics. How can you use these tools to decide the best path for your company to pursue? What are the pros and cons of using these tools?

Most of the first portion of our class explored the changes brought about by massive industrialization, urbanization, and immigration during the late nineteenth and early twentieth centuries. Which TWO of these three do you believe are the most important for understanding American history and why

Edward Jones (with a currently successful presence in the USA and Canada) is contemplating entering Asia (Singapore) and South America (Uruguay) net fall, for the first time.

Given that Singapore (index of 8) and Uruguay (index 100) rank respectively very low vs very high compared to moderately ranked US (index 46) and Canada (index 48) in terms of uncertainty avoidance, what marketing implications of this classification could you point out to Edward Jones as the company prepares to make its move? Discuss 1 from the 4Ps.

(1 point) The amount of paper used in a year per person in America has a normal (bell-shaped)distribution with a mean of 650 pounds and a standard deviation of 150pounds.

a)What percent of Americans use between200 and 1100 pounds of paper per year?

b)What percent of Americans use more than 800 pounds of paper per year?

c)What percent of Americans use more than 350 pounds of paper per year?

Carbon monoxide (CO) emissions from internal combustion engines increase in colder climates. Thus, the environmental damage from CO emissions is worse in the winter months than in the summer months. Nonetheless, air quality control authorities use a standard for CO that is uniform throughout the year with no allowance for seasonal effects. The cost and benefit information are as follows:

MSB of CO abatement in winter = 350 - 0.5A

MSB of CO abatement in summer = 140 - 0.2A

MSC of CO abatement = 0.2A

a. If you were in charge of setting a policy for CO emissions, what action would you recommend to ensure an allocatively efficient outcome across the two seasons?

b. Suppose that the government sets a uniform standard for winter and summer at A = 500. Determine the welfare loss associated with this policy.

Background

An American College conducted a study in the early 2000 to examine if there were any gender pay gaps[1] in its four schools: Business, Health, Liberal Studies and Sciences. Data were collected of a sample of 199 academics on their annual salary, years of service, rank, school, gender and age. The data file: Faculty Salary (Research Report Dataset).xlsx is available on Blackboard. A small portion of the data is shown below:

Legend: There are three academic ranks in the dataset: ASST, ASSO and PROF, which stand for Assistant Professor, Associate Professor and Professor respectively.

Task 1 (Boxplots and t-tests)

(a) Construct separate boxplots of salaries for male and female academics, and compare their distributions (central location, spread and skewness).

(b) Test if male academics on average earn more than their female counterparts at 1%.

                                                                                                                                        (1 mark)

(a) Considering assistant professors only, test if male assistant professors on average earn more than female assistant professors at 1%.

(1 mark)

(b) Considering associate professors only, test if male associate professors on average earn more than female associate professors at 1%.

(1 mark)

(c)   Considering professors only, test if male professors on average earn more than female professors at 1%.
