Respond to 2 classmates and answer all prompts for each required response.

Response 1: Respond to at least one classmate using the following:

• Lower the interest rate provided in your classmate’s post by one percentage point.
• Determine the amount of interest your classmate will pay with this new interest rate and how much money will be saved over the length of the loan.
• Write a 1-paragraph memo to your classmate explaining why the new interest rate is the better choice.

For response 1 you will respond to Sarah:

Sarah,

My husband and I have been throwing around the idea of purchasing a new pontoon boat. So, when this discussion came up, I figured it was perfect timing to do some figuring! The pontoon boat I chose had a sale price of $24,995.00, and a middle of the field interest rate for watercraft right now is 4.25%. Boat loans can range from 3-15 years depending on price, so I chose a term of 5 years or 60 months. I calculated the amount of interest that will be paid throughout the term of the loan using the following:

Interest= Principal*Rate*Time

I=$24,995*0.0425*5

The total amount of interest for the length of the loan is: $5311.44 (this is rounded for dollars and cents)

The final cost of the loan is determined by using this formula: principal + interest. Furthermore, $24,995+$5311.44= $30,306.44

The monthly payment for the pontoon is calculated with the following formula:

m= p*r(1+r) raised to n

(1+r) raised to n-1

m=24,995(.0425/12)(1+.0425/12) raised to 60

(1+.0425/12) raised to 60-1

m= (88.52)(1.23630214538)

.23630212

Monthly payment= $463.13 (rounded to dollars and cents)

If the loan term were lowered by one year, meaning the loan was taken out for 4 years instead of 5, the interest would be the following:

I= 24,995*.0425*4

I= $4,249.15

The total amount when paid in full after 4 years is: $29,244.15. This was calculated by adding $24,995+$4,249.15.

By using the above formula for calculating monthly payments, I simply changed the 60^th power to 48^th for 4 years in months is 48. The payment for 4 years would be: $567.14.

I am shocked that the payment amount was higher than I anticipated. However, I am not shocked that the four-year payment was $100 a month higher than the 5 year. Decreased time for the same amount of money equals a higher payment. My car is now paid off, but that payment was only $215 a month. Yes, that would contribute toward half of the pontoon payment, but I do not think I will be getting a pontoon anytime soon. Or at least a new one!!

Response 2: Respond to at least one other classmate using the following:

• Imagine that your classmate has signed up for a variable rate loan, which means that the interest rate can change.
• Assume that your classmate has paid back half of the loan when the interest rate increases by 5%.
• How much time is left on the loan?
• How much will need to be paid in interest during the second half of the loan?
• Explain to your classmate how much this interest rate change will affect the overall balance by comparing the original total cost to the new total cost. (Hint: Be sure to consider both the first half of the loan and second half when finding the new total payment.)

For the second response you will respond to Valerie:

Valerie,

The area that we live in you can find a really nice decent house for a good price, leave it to me to fall in love with a 550,000 house. This is out of our price range, by the way. Lol! Below is the cost after it is all figured out and the monthly payments as well.

Cost: $550,000

Interest Rate: 8%

Years: 10

Interest= Principal*Rate*Time

I=$550,000*.08*10=$440,000

$550,000+$440,000=$990,000

$990,000/120 months=$8,250 a month

Part 2;

Cost: $550,000

Interest Rate: 8%

Years: 9

I=$550,000*.08*9=$396,000

$550,000+$396,000=$946,000

$946,000/108 months=$8,759.26

Difference in monthly mortgage: $509.26

One thing I would do different is not purchase a house at this price. The difference in cost I thought would be more when you took a year off of the original equation.

Assignment Content

1. Competency
   This competency will allow you to demonstrate your ability and skill in analyzing zero-sum games and synthesizing optimal strategies within them. 
2.  Instructions
   A night club owner has just changed ownership and the new owner has contracted G&B consulting to help decide the direction the club will take. Based on the local music scene, it would make the most sense to book either rock bands or country bands. The new owner is aware that a competing night club is hoping to attract new customers while the new club is getting itself established. Since these are the only two night clubs in town competing to book the same bands, whatever market share is gained by one is lost by the other making this a zero-sum game. The new club owner has hired you to find the optimum strategy for this situation.

UNIT 6

Introduction

you will integrate your findings from Assessments 1–4 and describe how the survey was conducted. You will also reflect on the limitations of the survey and think about potential improvements for a future study.

Demonstration of Proficiency

By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies through the following assessment scoring guide criteria.

• Competency 1: Interpret a data set’s central tendency and variability using descriptive statistical procedures.
  • Interpret summary statistics for all survey questions.
• Competency 2: Evaluate the adequacy of data collection methods.
  • Evaluate constraints or limitations of conclusions based on survey results.
• Competency 3: Derive logical conclusions for inferential statistical calculations.
  • Derive logical conclusions for inferential statistical calculations.
• Competency 4: Solve problems in your personal and professional life by applying statistical procedures.
  • Interpret statistical analysis of data to explain the meaning of the survey results.
  • Explain the significance of survey results to research goals addressing an issue in one’s personal or professional life.
• Competency 5: Evaluate statistical arguments.
  • Recommend future study to further examine an issue in one’s personal or professional life.

In Assessments 1–4, you have gone through all steps from proposing a survey to producing and evaluating the survey data. For this assessment, you will analyze and integrate your findings from the previous components in Assessments 1–4. Write your paper from the viewpoint that you are presenting the information to an audience that is interested in your results. Include graphical representations as well as an explanation of descriptive and inferential measures, relating these components to the context of your survey. Only make claims that the data you collected can support.

The goal of your analysis and interpretation is to take the data that was collected and turn it into useful and usable information. Look for lessons that you learned from your data collection and results. What did you learn about the participants? What surprised you? Did you expect any of the results? Are there issues that arose that you did not understand? These may require further, more in-depth research. Discuss any limitations of the study.

In your paper:

• Interpret and communicate your results to your target audience.
• Include a brief summary of your population, sampling techniques, and survey.
• Communicate results, interpretation, and analysis of all assessments, including graphs (circle, bar, histogram), measures of central tendency, measures of variation, confidence intervals, and hypothesis tests.

Your paper should contain both a summary of results and an interpretation and analysis of the results. Every survey question should be addressed in your interpretation. You will not be able to comment on every little finding, so you will have to make some judgments about what might be the most interesting or revealing results.

Cerámica América makes both commercial and home sinks, toilets, and tile throughout Latin America. There have been many complaints that its commercial sinks are of poor quality. Recently, a new type of home sink, Modelo Americano, has been developed. The company hopes that this new model is of better quality. Quality Control tests sinks using the following three tests:

1. Cracked or Chipped Ceramic:

Pass (P) or Fail (F)

1. Glaze Quality:

Pass (P) or Fail (F)

1. Stress Test

Pass (P) or Fail (F)

A sink gets a “Passing” grade if it passes all three of the above tests. Traditionally, 85% of its commercial sinks have gotten a “Passing” grade. Cerámica América would like to see if its passing rate is better than the traditional rate. Recently, 200 Modelo Americano sinks were randomly chosen from its manufacturing plants. The complete data set is in the file named Sinks.

Managerial Report

Prepare a report (see below) for Cerámica América that summarizes your assessment of its Modelo Americano sinks. Be sure to include the following seven items in your report.

1. To summarize the data, compute the proportion of all sinks that
   1. “Passed” the Cracked or Chipped test.
   2. “Passed” the Glaze Quality test.
   3. “Passed” the Stress Test.
2. What do these three proportions tell you about the quality of sinks at Cerámica América?
3. What graphical displays of data would you use to understand or explain the results of the survey?
4. What is the point estimate of the proportion of all Modelo Americano sinks that got a “Passing” grade? Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that got a “Passing” grade. Interpret what the confidence interval tells you about the proportion of all Modelo Americano sinks that got a “Passing” grade. What is the corresponding margin of error? How can the margin of error be decreased?
5. Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Cracked or Chipped test. Interpret what the confidence interval tells you about the proportion of all Modelo Americano sinks that passed the Cracked or Chipped test. What is the corresponding margin of error? How can the margin of error be decreased?
6. Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Glaze Quality test. Interpret what the confidence interval tells you about the proportion of all Modelo Americano sinks that passed the Glaze Quality test. What is the corresponding margin of error? How can the margin of error be decreased?
7. Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Stress test. Interpret what the confidence interval tells you about the proportion of all Modelo Americano sinks that passed the Stress test. What is the corresponding margin of error? How can the margin of error be decreased?
8. Conduct a hypothesis test, using both the p-Value Approach and the Critical Value Approach, to determine if the proportion of all Modelo Americano sinks that get a “Passing” grade is larger than the traditional “Passing” rate. Use α = 0.02 level of significance. Do not forget to include the correctly worded hypothesis and show all of the steps required to conduct the hypothesis test.
   1. What would be possible effects of a lower and then of a higher level of significance?
   2. What other hypothesis tests would you use to better understand the quality of the sinks.
   3. What advice would you give to Cerámica América based upon your analysis of the data?
   4. What is the magnitude of the improvement (if any)?
   5. How can this study be improved?
