Project Part B: Hypothesis Testing and Confidence Intervals
Your manager has speculated the following:
a. the average (mean) annual income was greater than $45,000.
b. the true population proportion of customers who live in a suburban area is less than 45%.
c. the average (mean) number of years lived in the current home is greater than 8 years.
d. the average (mean) credit balance for rural customers is less than $3200.
Using the sample data, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case a.-d. In each case use the Seven Elements of a Test of Hypothesis, in Section 6.2 of your text book with α = .05, and explain your conclusion in simple terms. Also be sure to compute the p-value and interpret.
Follow this up with computing 95% confidence intervals for each of the variables described in a.-d., and again interpreting these intervals.
Write a report to your manager about the results, distilling down the results in a way that would be understandable to someone who does not know statistics. Clear explanations and interpretations are critical.
Project Part C: Regression and Correlation Analysis
Using MINITAB perform the regression and correlation analysis for the data on CREDIT BALANCE (Y) and SIZE (X) by answering the following.
1. Generate a scatterplot for INCOME ($1000) vs. CREDIT BALANCE($), including the graph of the “best fit” line. Interpret.
2. Determine the equation of the “best fit” line, which describes the relationship between INCOME and CREDIT BALANCE.
3. Determine the coefficient of correlation. Interpret.
4. Determine the coefficient of determination. Interpret.
5. Test the utility of this regression model (use a two tail test with α =.05). Interpret your results, including the p-value.
6. Based on your findings in 1-5, what is your opinion about using CREDIT BALANCE to predict INCOME? Explain.
7. Compute the 95% confidence interval for beta-1 (the population slope). Interpret this interval.
8. Using an interval, estimate the average income for customers that have credit balance of $4,000. Interpret this interval.
9. Using an interval, predict the income for a customer that has a credit balance of $4,000. Interpret this interval.
10. What can we say about the income for a customer that has a credit balance of $10,000? Explain your answer.
11. In an attempt to improve the model, we attempt to do a multiple regression model predicting INCOME based on CREDIT BALANCE, YEARS and SIZE.
Using MINITAB run the multiple regression analysis using the variables CREDIT BALANCE, YEARS and SIZE to predict INCOME. State the equation for this multiple regression model.
12. Perform the Global Test for Utility (F-Test). Explain your conclusion.
13. Perform the t-test on each independent variable. Explain your conclusions and clearly state how you should proceed. In particular, which independent variables should we keep and which should be discarded.
14. Is this multiple regression model better than the linear model that we generated in parts 1-10? Explain.
Objective
This project introduces the Brics and Mitsk countries and integrates the concepts presented in weeks 1-4. It also provides a common foundation for future discussions.
Guidelines
Prepare a PowerPoint Presentation based upon a Brics and Mitsk Country: Brazil, Russia, India, China South Africa, Mexico, Indonesia, Turkey and South Korea. These countries have been identified as important emerging countries that are significant economic powers individually, as well as becoming the basis of an important new economic group. It is important to develop an understanding of these countries – for the purposes of understanding global business strategy, and the opportunities and threats they pose.
Your country choice should be approved by your professor in Week 1.
· Please develop a set of slides that would help an organization contemplating doing business in the country you have been assigned.
· Please focus you analysis on Porter’s Diamond of National Advantage.
· Please provide images and key facts that capture the economic conditions and culture.
· Please develop a presentation with approximately 15 slides.
A successful project will earn a maximum of 200 points demonstrating:
· Accurate, relevant and timely research
· PowerPoint slides that include good quality content, clear and compelling, yet professional presentation style.
Milestones
· Week 1: Identify country and obtain Professor’s approval.
· Week 2-3: Research and prepare slides.
· Week 4: Submit PowerPoint for grading and upload to the Drop box.

I need you to help me with the section 3,5,7,8. We have choosed the companies which are Lowe’s and Home Deport. The requirement of the two companies are in the attachment.
Thank you! If you have any questions, plz let me know.
Lab project need to be completed.
***statman*** i will need your assistance with this as you are native to this country.
i have theater 110 online . i need someone take this subject for me for the whole semester and get A for guarantee
Do not send handshake unless you are Perfect Prof, thank you.
