Chapter 8 (a through e)
Problem 1

a. Given that the nominal wage rate equals 50, the equation for the short-run aggregate supply curve is Y = 11,250 – 20(50) 1,000P = 10,250 + 1,000P. The amount of short-run aggregate supply when the price level equals 2 is 10,250 + 1,000(2) = 12,250. The amount of short-run aggregate supply when the price level equals 1.25 is 10,250 + 1,000(1.25) = 11,500. The amount of short-run aggregate supply when the price level equals 1 is 10,250 + 1,000(1) = 11,250. The amount of short-run aggregate supply when the price level equals .8 is 10,250 + 1,000(.8) = 11,050, and it equals 10,250 + 1,000(.5) = 10,750 when the price level equals .5. The points on the short-run aggregate supply curve are: (10,750, 0.5); (11,050, 0.8); (11,250, 1.0); (11,500, 1.25); and (12,250, 2.0).

b. Given that the nominal wage rate equals 50, the equation for the short-run aggregate supply curve is Y = 11,250 – 20(50) + 1,000P = 10,250 + 1,000P. The amount of short-run aggregate supply when the price level equals 2 is 10,250 + 1,000(2) = 12,250. The amount of short-run aggregate supply when the price level equals 1.25 is 10,250 + 1,000(1.25) = 11,500. The amount of short-run aggregate supply when the price level equals 1 is 10,250 + 1,000(1) = 11,250. The amount of short-run aggregate supply when the price level equals .8 is 10,250 +1,000(.8) = 11,050, and it equals 10,250 + 1,000(.5) = 10,750 when the price level equals .5. The points on the short-run aggregate supply curve are: (10,750, 0.5); (11,050, 0.8); (11,250, 1.0); (11,500, 1.25); and (12,250, 2.0).

Week Three Reflection Summary

...Week Three Reflection Summary Anna Delarosa RES 351 February 3, 2014 Dr. Joseph Oloyede Week Three Reflection Summary Within our third week, the team was tasked with the objective to differentiate between qualitative and quantitative methods of research. Next, the team was asked to explain the commonly used qualitative research designs and quantitative research designs. Finally the team was the asked to identify how to select appropriate research designs in any given situation. Quantitative research attempts to achieve precise measurement of something; often the responses received are veiled, classified, and condensed to numbers to be manipulated for statistical analysis (Cooper & Schindler, 2011, p. 164). The insights gained from completing this research is limited by the opportunity to probe respondents, and the quality of the original data collection instrument. Additionally, this will follow data collection and data entry, with a small window of opportunity to circle back with survey participants. In contrast, qualitative research is intended to tell the examiner how and why things happen as they do, it also aims to achieve a thorough understanding of a situation. The expected result or insights with this method provide a more profound level of understanding; which is determined by the type and amount of open-ended questions. Using qualitative research allows the researcher to inform insights and test them throughout the study process. ......

NIMS (National Incidence Management System) also known as FEMA. When there is a natural disaster, emergency crews (fire department, ambulance, police etc.) is usually the first help on the scene to help people out. Socialism system offers the best solution for handling emergency situations because the government takes care of paying the people who work there so everyone can focus on helping the people in need. Being a not for profit organization means that everyone doing what they are supposed to and looking after injured people's best interest. Socialism in its perfect form (which rarely ever happens) seems to be the best economic system because it teaches people how to share things with your neighbor and to help out on the time of need. Describe and explain why a socialist system might be the best in responding to the needs of people struck by an emergency situation like the earthquake that occurred in Haiti in January 2010. A socialist society is more likely to have immediate and controlled impact on an emergency situation like the ones suffered in recent years throughout the world. Socialist societies are base in the good of the nation and the human needs of the people making them more efficient in regrouping and reorganizing their efforts.

Week Three Problems

...University of Phoenix Material Week Three Practice Problems Prepare a written response to the following questions. Chapter 4 11. List the five steps of hypothesis testing, and explain the procedure and logic of each. 1. “Restate the question as a research hypothesis and a null hypothesis about the populations”. One makes a research hypothesis about a predicted correspondence among populations. The research and the null hypothesis’ are opposites, meaning if one hypothesis is correct and true the other is not. 2. “Determine the characteristics of the comparison distribution”. This is important because the comparison distribution represents the population situation if the null hypothesis is factual. This is the main idea of hypothesis testing. 3. “Determine what the cutoff sample scores on the comparison distribution where the null hypothesis should be rejected”. This means determining a target against the results that will be compared or to what extreme the sample score would have to be for it to be too doubtful that they could get such an extreme score if the null hypothesis were true. Here the null hypothesis would be rejected if the point of the cutoff sample scores reaches or exceeds the sample score. If the null hypothesis is true the Z score is established at a score which would be improbable. 4. This step is to get the actual results for the sample. “Determine your sample’s score on the comparison distribution” . After one gets......

The Federal Trade Commission and the Federal Reserve Board was seeking amendments to the Risk-Based Pricing Rule that would require creditors, as of July 21, 2011. I am starting my own business so this interests me as to how the credit scores are reported to the consumers. 2. The proposal makes the creditors to disclose the credit score information to the consumers when a credit score is used in setting or adjusting credit terms. Also consumers who receive the notice can obtain a free credit report to check the report’s accuracy. As an alternative to providing the notice, the Rule permits creditors to provide credit applicants with a free credit score and information about their score. 3. The agencies should provide additional information related to credit scores to the risk-based pricing notices. Specifically, the risk-based pricing notice include an explanation that the consumer does not have a single credit score, and that the credit score may vary with the consumer reporting agency and a particular credit product for which the consumer applied. Most consumers need this information to help them understand why they are receiving a particular score that may not be the same as a FICO score. 4. All the comments must be received by 04/14/10 and comments on he Paperwork Reduction Act analysis set forth in Section III.A. of this Federal Register notice must be received on or before May 16, 2011. 5. a. 1.

In your experience what tools and techniques have you seen used effectively? As a contributor to inaccurate duration estimates is a situation known as Parkinson’s law. He further described “work expands so as to fill the time available for its completion”. This means that if we estimated an activity will take two weeks, it’ll end up taking two weeks even if it could have been finished in one. Tools and techniques that project managers can take to overcome Parkinson’s Law.
