1. In a study of the effect of anxiety on the need for affiliation, participants were told either that they would either be giving a speech to a large audience of peers (high anxiety) or that they would be speaking to one experimenter (low anxiety). Subjects were then given a choice between waiting alone before speaking or waiting in the company of others. Below are the number of participants who chose to wait alone or with others in the high and low anxiety conditions. Test the null hypothesis that anxiety had no effect on whether people chose to wait alone or with others. (34 points)

For each of the following questions, please specify what statistical test should be used. The correct answer can be any test that we covered this semester from correlation through chi square. (4 points each)

3. In a test of the decay theory of memory, participants memorized a list of nonsense syllables and were tested for recall after one hour and then four hours. What statistical test should be used to test the null hypothesis that delay had no effect on their recall scores?

4. Researchers are interested in whether the way instructions are delivered to jurors affects their decision making. They have two groups. In one group the jurors are verbally given instructions from the judge. In the second group the jury is given written instructions to read. What test would the researchers use to test the null hypothesis that how the instructions are given does not affect the jury’s decision making process?

5. A teacher thinks that she has an especially gifted class. She wants to compare their standardized test scores to those for the entire population of 4th graders. She knows that district wide the average exam score was a 430 with a standard deviation of 12. Her class of 18 students scored a 495. What test would you use to test the null hypothesis that her class did not do score higher than the rest of the district?

6. An experimenter is interested in testing whether listening to music improves learning how to solve complex equations. She has a control group complete a learning task without music and then an experimental group that listens to current popular music while completing the same task. What test would you use to test the null hypothesis that music does not have an effect on learning?

7. A professor believes there is a relationship between attendance and test scores. What test would she use to test the null hypothesis that there is no link between attendance and performance on a test?

8. Administration at a university believes that students who live on campus during the semester have higher levels of satisfaction with their experience at the university than students living in different off campus options. They sample 20 students who live on campus, 20 who live with roommates in off campus housing, and 20 who live at home with their families while attending classes, and then measure their satisfaction with their experience as students at the university. What test would the researchers use to test their hypothesis about student satisfaction?

9. The director of a juvenile drug rehabilitation center wants to see how their relapse rates compare to the state average. She knows the state average, but does not know the standard deviation for the state’s relapse rate. What test would she use to test the null hypothesis that her facility does not differ from the state average?

10. The matching hypothesis states that partners in romantic relationships tend to be well matched for attractiveness. Researchers are interested in seeing if this hypothesis generalizes to same sex couples. The researchers collect pictures of the faces of both partners in 30 same sex relationships, and have a group of trained coders rate how attractive each partner is. What test would the researchers use to test the null hypothesis that there is no difference in the attractiveness of same sex partners?

The Inside Story of the 1996 Welfare Reform. The work is to be 1 page with three to five sources, with in-text citations and a reference page.

I will pay for the following article The Inside Story of the 1996 Welfare Reform. The work is to be 1 page with three to five sources, with in-text citations and a reference page. They may simply be living off other taxpayers. Money has been taken from those who work hard and give to those who don’t work. The result is that the taxpayer is actually poorer than before and the poor person is a little richer. This may reduce the overall levels of depredation, but the amount of money or productivity has not increased. So this is not really effective.

What would be a more effective use for many of the able-bodied people who currently receive benefits would be to work on large infrastructure projects in order to receive their benefits. These jobs may be hard, but these individuals are under no compulsion to do the work. If they don’t want to do the job that is fine, but they will not be paid. We need to get past the idea that able-bodied individuals should be able to live off other taxpayers. This just creates dependence and leaves no one better off than before.

examine the following questions from you selected country and product. • What are some of the key cultural, ethical and social responsibility that you should be mindful of when developing the strategy for your country and product? • What social responsibility efforts are you going to pursue in your host country? 300words the country chooses the same for the week one. Another dox is last week you give me that answer, that is you choose the country, only 1 page was enough.

Write a 13 pages paper on leed sustainable construction project. The site amenities will include a pathway, parking lot, and an outdoor gathering space. The configuration of the building will include the training rooms, board rooms, conference rooms, and commercial offices for tenants. Additionally, the project will have a certification from LEED.

Write a 13 pages paper on leed sustainable construction project. The site amenities will include a pathway, parking lot, and an outdoor gathering space. The configuration of the building will include the training rooms, board rooms, conference rooms, and commercial offices for tenants. Additionally, the project will have a certification from LEED.

LEED sustainable construction project is designed to change the built environment. The project has proved performance where nothing comes so easily. When thinking of saving money, reducing consumption of water, driving innovation, conserving energy, improving the quality of indoor air, and making proper choices of building materials, then LEED has proven to be the proper choice. LEED construction project is assisting in delivering the efficiency of water and energy, health, a building that are environmentally cost-saving, communities, and homes. LEED construction project is more than the credits and the points. Behind the program of LEED, there is an infrastructure that is immensely developed in supporting the leaders in the section during innovation and creation of cutting edge, buildings of high performance, neighbourhoods and homes. For instance, USGBC invested more than 30 million dollars in maintaining, operating and improving LEED and customer delivery. There is no single rating system that nears the infrastructure of LEED. The first step is the project registration. Registering the project will open the door to award-winning customer and resources (Hove &Tong, 28).

Each LEED project has access to LEED online. The LEED online is a convenient and clear instrument to document the achievement of LEED credit. Additionally, the registered project will get access to customer service. Here the user will interact with the project viewer, account managers, customer service team, and representatives from the business team, and experts from the LEED department. Additionally, they will get access to the professional infrastructure.
