What do you see when you compare the coefficients on RootCause estimated in those two regressions? Why do we see those results in 2 and 3?

Math/Physic/Economic/Statistic Problems

Create a 1000 observation dataset. Generate variables RootCause and OtherThing as independent, uncorrelated variables each drawn from a normal distribution with mean 0 and variance

1. Create a set of normal error terms with mean 0 and variance 1. Let Outcome = 1 + RootCause + 3OtherThing + errors.

1. Draw a graphical representation of the data generating process (DGP) involving the variables Outcome, RootCause, and OtherThing, that is, show by drawing arrows how these three variables relate to each other in the data you generated. Are RootCause and OtherThing independent?

If you think they are independent, how would you represent graphically that they are independent in your DGP? If you think they are not independent, how would you represent graphically that they are not independent in your DGP?

2. Regress Outcome on RootCause. Report and interpret the result. Did you estimate the causal effect of RootCause on Outcome with this regression? Did you estimate the causal effect of RootCause on Outcome with this regression?

If you think you were able to estimate this causal effect, why do you think you were able to do so with this regression? If you think you were not able to estimate this causal effect, why do you think you were not able to do so with this regression?

3. Regress Outcome on RootCause and OtherThing. Report and interpret the result. Did you estimate the causal effect of RootCause on Outcome?

If you think you were able to estimate this causal effect, why do you think you were able to do so with this regression? If you think you were not able to estimate this causal effect, why do you think you were not able to do so with this regression?

4. Compare the results of the regressions you ran in 2 and 3.

Problem set 8

Clear your work space and create a new data set with 1000 observations. Generate variable RootCause following a normal distribution with mean 0 and variance

1. Generate variable OtherThing = 2RootCause + noise where noise follows a normal distribution with mean 0 and variance 1. Create a set of normal error terms with mean 0 and variance 1. Let Outcome = 1 + RootCause + 3OtherThing + errors.

1. Draw a graphical representation of the data generating process (DGP) involving the variables Outcome, RootCause, and OtherThing, that is, show by drawing arrows how these three variables relate to each other in the data you generated.

2. Regress Outcome on RootCause. Report and interpret the result. Did you estimate the causal effect of RootCause on Outcome with this regression?

If you think you were able to estimate this causal effect, why do you think you were able to do so with this regression? If you think you were not able to estimate this causal effect, why do you think you were not able to do so with this regression?

3. Regress Outcome on RootCause and OtherThing. Report and interpret the result.

Did you estimate the causal effect of RootCause on Outcome? If you think you were able to estimate this causal effect, why do you think you were able to do so with this regression? If you think you were not able to estimate this causal effect, why do you think you were not able to do so with this regression?

4. Compare the results of the regressions you ran in 2 and 3. What do you see when you compare the coefficients on RootCause estimated in those two regressions?

Why do we see those results in 2 and 3? In your answer, explain how those results are related to the question whether the regression of Outcome on RootCause and OtherThing meets the conditional independence assumption.

Identify Carr’s metaphor, then put an arrow, then put your metaphor, then write a paragraph using that metaphor to make a point about using the Net. Put the metaphors in bold- “Is Google Making Us Stupid?”

“Is Google Making Us Stupid?”

MAX=> 100 words.

RESPONSE: Take a metaphor used by Carr (jet-skier, brain as computer, shallows, depths, cathedral, etc.) and come up with a similar metaphor and a scenario which makes a point about how you (or other people) are effected by the Internet.

Make sure not to use the exact same metaphor Carr uses. For instance, where Carr uses a cathedral, you might use a Greek temple, a gurdwara, a mosque, a synagogue, Yankee Stadium, the British Museum, or the downtown Vancouver library.

You can use your own experience, create a fictional scenario, or give an explanation. Remember that the response must be in one paragraph and cannot exceed 100 words.

FORMAT: Identify Carr’s metaphor, then put an arrow, then put your metaphor, then write a paragraph using that metaphor to make a point about using the Net. Put the metaphors in bold.

How does Social Media help fight negative sterotypes?

Following the Topic Selection Guidelines below, choose an argumentative topic to research. This will be your topic throughout the entire course, so the activities required for this assignment will provide the foundation for your future Touchstones.

The topic for an argumentative research paper must be a debatable topic, meaning that it involves conflicting viewpoints. Additionally, it cannot be a topic that is already decided or agreed upon by most of society.

You will need to take a firm position on the topic and use evidence and logic to support the position. Touchstone 1.2 includes a research question, a working, a detailed outline, and a reflection on this pre-writing process.

Below your assignment, include answers to all of the following reflection questions.

Learning to conduct research is important because it is a skill you will use both in academia and in your professional life. It improves critical thinking and empowers you to find information for yourself.

Consider the process of researching as a whole. What was the most challenging aspect of the process for you? (2-3 sentences)

The working  statement is a proposed answer to your research question. It should clearly identify a debatable topic and take a position on one side of that topic. Analyze the effectiveness of your working  statement. (3-4 sentences)

A detailed outline is an effective tool for laying out the progression of an argument. It allows you to consider the arrangement and organization of your ideas, as well as choose places to incorporate outside source materials. Review your detailed outline and summarize the argument you’ve presented. (3-4 sentences)

You will use the same topic on three of the remaining Touchstones in this course. What kind of feedback would be helpful for you? What are specific questions you might have as you go deeper into the research process? (2-3 sentences)

Determine the appropriate ventilation control and calculate the capture velocity.If it is necessary to modify the PEL, explain the reasoning why it is to be modified.

Employee Exposure Limits to Hexane

As the environmental health and safety (EHS) manager, you have been asked to evaluate an existing operation to determine employee’s current exposure to hexane, which is a chemical used in painting processes.

You are to complete an evaluation of the employee’s current exposure by determining the employee’s exposure to hexane (toxic contaminant) by calculating time-weighted average (TWA) and compare it to the permissible exposure limit (PEL) and modify the PEL, if necessary.

If it is necessary to modify the PEL, explain the reasoning why it is to be modified.

Once the Current exposure has been determined, select the appropriate ventilation system between dilution and local exhaust that is the best choice to control the concentration of the contamination.

Ensure that you provide the reasons why you think your Selection of ventilation system is the best choice. You are to provide the results in a three-page project report using the Unit

III Consulting Report template.

Scenario

An employee working in a room measuring 15 ft x 20 ft x 15 ft sprays paint assembly parts using a paint containing hexane.

The PEL for hexane is 500 ppm. The employee wears a half-face, air-purifying respirator, but management would like to

install engineering control measures to reduce or eliminate the employee’s exposure to hexane. The options are to:

(1) install a dilution ventilation system, or

(2) install a local exhaust ventilation system.

The employee works a 9-hour shift and has the following exposures:

Sample 1 – Concentration 550ppm – Sampling Time – 1.5 hours

Sample 2 – Concentration 400ppm – Sampling Time – 5.8 hours

Sample 3 – Concentration 375ppm – Sampling Time – 1.7 hours

For the general dilution ventilation system to work, there must be at least 20 room air changes per hour. The fan which supplies air to this area produces 1,500 cubic feet per minute (cfm) (Q).

In order for the local exhaust ventilation system to remove the contaminant to acceptable concentrations, the capture velocity must be at least 140 feet per minute (fpm).

The proposed local exhaust system ventilation system uses a 1.0 feet
diameter duct and a fan that provides a total volume of 1,275 cubic feet per minute (cfm). The source of the contamination is located 1.5 feet from the opening of the duct.

Determine the appropriate ventilation control and calculate the capture

velocity.

Complete your project by following the Unit III Consulting Report template linked above. Ensure you show your equations and all work for determining answers for all three scenarios in the project document. You may either formulate the scenario Equations using the Word equation formula toolbar or write out and solve your equations with answers on a separate paper.

Then, take a screenshot of your work for each scenario using your phone or similar device and insert it as an image in the Document. Make sure your image is clear and legible to read.
