query one: Create a pl/sql block using for loop to generate a payment schedule for a donors pledge, which is to be paid monthly in equal increments. Values available for the block are starting payment due date, monthly payment amount and number of totally monthly payments for the pledge. the list that is generated should display a line for each monthly payment showing payment number, date due, payment amount and donation balance (remaining amount of pledge owned).

query two: accomplish the task in step on by using a while loop instead of displaying the donation balance on each line of output, display the total paid to date.

**Initialize your own values, there is no table to pull data from**

I will pay for the following article Factors for the Cross Cultural Research and Surveying in International Marketing Research. The work is to be 6 pages with three to five sources, with in-text citations and a reference page. Global trends of political and economic liberalization have created tremendous business opportunities as well as challenges for global marketers. The information has been considered to be a key component in developing successful marketing from global opportunities and meeting the challenges by avoiding marketing blunders. Information can be either acquired through research or bought from trusted research vendors. Entering into a new foreign market is one of the most daunting and ambiguous marketing strategic decisions that needs careful and intensive market research so as to assess the opportunities to specific market information for decisions regarding product, promotion, distribution, and pricing, etc. &nbsp.

Ember and Ember (2009) stated that the term cross-cultural refers to any kind of comparison between different cultures. The cross-cultural research focuses on systematic comparisons that aim to answer the questions about the incidence, distribution, and causes of cultural variances (p. 2). The cross-cultural researchers usually apply standards principles of scientific methods and research design, with the help of random or other sampling methods that are assumed to be unbiased, reliable, and dependable so that others can replicate the results (Ember and Ember, 2009, p. 3).

Cross-cultural research has been a significant part of the anthropological discipline in which researchers have worked with different people of different cultural and social settings mainly by using ethnography for the data collection (Liamputtong, 2008, p. 3). Entering into a new country remains to be a marketing challenge because, different countries have different cultures and social backgrounds therefore it is imperative that researchers increasingly need to ensure that their work should be conducted ethically and considering the cultural norms as well.

While conducting cross-cultural marketing research, there are various issues that researchers are to consider and make necessary arrangements so as to solve the issues.&nbsp.&nbsp.

Math 221 − Lab Week 2

Name:

Statistical Concepts:

• Using Statcrunch

• Graphics

• Shapes of Distributions

• Descriptive Statistics

• Empirical Rule

Follow the directions for each problem and then answer the questions that follow in the space provided. 

Background Info:  The American International Group (AIG) was once the 18th largest corporation in the world. In 2004, AIG stock hit an all-time high of $76.77, putting its market value at nearly $300 billion.  By early 2007 AIG had assets of $1 trillion, $110 billion in revenues, 74 million customers and 116,000 employees in 130 countries and jurisdictions. Yet just 18 months later, AIG found itself on the brink of failure and in need of emergency government assistance. AIG was one of the largest beneficiaries of the U.S. government’s Troubled Asset Relief Program (TARP), established in 2008 during the financial crisis to purchase assets and equity from financial institutions.  Between 2007 and 2009 AIG stock lost more than 99% of its value, hitting $0.35 in early March.  (Source: Business Statistics, 3rd edition, Norean D. Sharpe) 

Dataset “AIG Stock Prices” gives the monthly average stock price (in dollars) from 2002-2007, which was the six years leading up to the company’s crisis. This dataset can be found under Files, Week 2, Datasets.

1. Create a histogram for the monthly average stock prices 

• Open up the Statcrunch program.

• Copy the non-rounded stock price data from Excel and paste it into Statcrunch (use CTRL + V to paste).  

• Click on Graph, then Choose Histogram.

• Click on the variable name under Select Column(s).

• Under Bins, enter 45 for Start At and 5 for Width

• Under Display Options, check Value Above Bar

• Under Markers, check Mean

• Under Graph Properties, label the x-axis “Average Stock Price (in dollars)”, the y-axis “# of Months (2002-2007)”, and the chart title “AIG Monthly Stock Prices from 2002-2007”. 

• Click on Compute.

• Right click on image and choose Copy Image

• Paste in the gray field below by pressing (CTRL + ALT + V) then choose Device Independent Bitmap.

a. Describe the shape of the distribution of the monthly average stock prices. (i.e. Is it symmetric, uniform, 

  skewed, etc? If skewed, what type of skewness?) 

b. Using the histogram, how many months between 2002 and 2007 had a monthly average stock price less 

  than $65? 

c. The green vertical line represents the mean of the monthly average stock prices. Give a best estimate for 

  it from the graph. 

a.  

b.  

c.  

2. Stem-and-Leaf Plot for Rounded Monthly Average Stock Prices 

Using the same AIG dataset, construct a stem-and-leaf plot for the Monthly Average Stock Prices. For your convenience, stock prices have been rounded to the nearest whole number.   

Steps to Create a Stem and Leaf Plot in Statcrunch:

• Open up Statcrunch

• Copy and Paste the rounded stock prices into Statcrunch

• Click on Graph, then Choose Stem and Leaf.

• Click on the variable title for the rounded stock prices.

• Hit Compute

• To copy, highlight the stem-and -leaf plot and paste it into the answer field below.

a. Compare the shape of the distributions from the stem-and-leaf plot and the histogram above. What can you

   conclude? Is this surprising to you? Explain.

b. If you had to find the median monthly average stock price from the stem-and-leaf plot, explain how you would 

   go about doing so. What is the median monthly average stock price? 

c. From the graph, find the mean for the 6 largest monthly average stock price.

a.

b. 

c.

3. Boxplot for Monthly Average Stock Prices

Using the AIG dataset, construct a boxplot for the variable monthly average stock prices. Follow the steps below:

• Open up Statcrunch

• Use the non-rounded monthly average stock prices.

• Click on Graph, then choose Boxplot.

• Click on the appropriate variable.

• Under Other Options, check “Draw Boxes Horizontally”.

• Under Graph Properties, as in part 1, enter an appropriate x-axis label (include units) and a title.

• Hit Compute

• Copy and paste below following the same instructions as on the Histogram.

a. Give the 5-number summary.  (Hint: Hover cursor over boxplot)  

b. What percent of all monthly average stock prices fall within Q1 and the max value?

c. What does the line within the box represent and what is its value?

d. If you had to find the range for the dataset using the box plot values, how would you find it? What is the 

   range?

a.

Min = 

Q1 = 

Q2 = 

Q3 = 

Max = 

b.

c.

d.

4. Calculating Descriptive Statistics for Monthly Average Stock Prices

Using the AIG dataset, use the tools you learned in week 1 to find the descriptive statistics for the non-rounded monthly average stock prices. Fill in the table below. Round answers to two decimal place, when appropriate.

Mean

Median

Range

Variance

Standard Deviation

Price

a. What statistics above are values that describe the central tendency of the data?

b. What statistics above are values that describe the variation of the data?

c. All statistic above have the same units, except for one of them. Which statistic has different units and what are its units?  

a.

b.

c. 

5. Empirical Rule for Monthly Average Stock Prices

 Although the Monthly Average Stock Prices have a slight skewness, it can be argued that it does follow an approximately bell-shaped distribution. Use what you learned in week 1 about the Empirical Rule to answer the questions that follow. It will be helpful to draw the distribution on a scratch paper and label it using the mean and standard deviation that you found in part 4 above. See your week one lecture notes.  

a. 95% of the monthly average stock prices between 2002 and 2007 fell between what two values? Either show the math calculations or explain in words how your answers were calculated.

a. 

b. 68% of the monthly average stock prices between 2002 and 2007 fell between what two values? Either show the math calculations or explain in words how your answers were calculated.

b. 

Upon completing this lab, save it by including your name at the end of the file name. Under Modules, Week 2: Lab, upload your saved document and submit it by the due date of Sunday, 1/14 by 11:59pm.

Before effective Ethernet switching existed, some network designers used an alternative bus collision avoidance protocol known as the token bus protocol. With the token bus protocol, a ‘‘token’’ made up of a short, standard string of 1s and 0s was circulated constantly in a round robin fashion among the Network Interface Units (NIUs) attached to the bus. NIUs did not hold the token; they simply passed it without delay to the next NIU in the chain. An NIU was only allowed to place a message on the bus when it possessed the token. After the message was delivered, the token was again put into circulation. No NIU was allowed to use the token again until the token had circulated to every other NIU at least once. (a) Under what conditions would this protocol perform more satisfactorily than CSMA/CD? Explain.
