Decide on the two grocery stores to use in this activity

Decide on the 15 products you want to compare.

The brand name, product, and size have to be exactly the same at each store. Therefore, do not compare generic brands as they have different names at different stores.

You may have to wait until your visit to the first store to determine the “size” as you may not be aware of the different size packages for different products.

Use a variety of products to get a good representation of all items at the stores.

At each store, record the price of each product on your list. (A question always comes up whether to use a sales prices or a club card price. You should use the price of the item that you’d pay on the particular day you visit the store.)

If you didn’t record the prices in an electronic spreadsheet (such as an Excel spreadsheet) at each store, do so after you collect all your data.

Questions to answer after collecting your data

The question of interest is, “Are the items at one of the two grocery stores in your study more expensive, on average, than the other store?”

Answer these questions to answer the question of interest. (R tutorial 2 may be helpful in answering some of these questions.)

1.   (1 point) Give the two stores you are comparing and a personal motivation on why you chose those two stores.

2.   (2 points) Give a brief summary of how you chose the 15 items you used in the study. Do you feel these items are representative of all items at the store? (In other words, do you feel that you’ll be able to answer the question of interest based the items in your sample?) Why or why not?

3.   (3 points) What method of inference you used and why? (Include a check of the conditions to use that particular method. If you use a graph to assess any condition, include the graph) (Hint: think about the samples you took – are the samples independent or dependent?)

4.   (3 points) State the null and alternative hypotheses in statistical notation. Define any parameters used.

5.   (2 points) Obtain and include an appropriate graphical display that will allow you to make an initial guess as to whether you feel the null hypothesis will be rejected or not. (Hint: think about what method you will be using to perform the hypothesis test.) Comment on whether or not you feel the null hypothesis will be rejected and why or why not.

6.   (1 point) Perform the analysis in R. Report the test-statistic (with degrees of freedom) and p-value.

7.   (3 points) State a conclusion in the context of the problem that answers the question of interest supported with the p-value obtained in #6.

8.   (3 points) Use R to construct a 95% confidence interval for the average difference in prices between the two stores. Include and interpret the confidence interval in the context of the problem. (3 pts)

9.   (2 points) Which store would you shop at? Why?

10. (2 points) Provide a copy of your data.

For this coding exercise, you need to create a new Java project in Eclipse and finish all the coding in Eclipse. Run and debug your Eclipse project to make sure it works. Then you can just copy and paste the java source code of each file from Eclipse into the answer area of the corresponding box below.

The boxes will expand once you paste your code into them, so don’t worry about how it looks J

All data members are private and all methods are public in each class/interface in the exercise below.

Creare a class named CreditCard, which has three private data members:

1. domesticSpending of double type,
2. foreignSpending of double type,
3. and basicFeeRate of double type.

Provide:

1. default constructor with no parameters,
2. constructor with three parameters to initialize its three data members, respectively.
3. getter/setter methods for each data member

There are two effector methods:

1. Method calcBasicFee() takes no parameters and it returns a double type.
   1. This method calculates the basic transaction fee by multiplying the basicFeeRate with the sum of domestic and foreign spending.
   2. For example, if a person has $100 and $50 in domestic and foreign spending, respectively, then under a basicFeeRate of 2% (0.02), the credit card company will charge 0.02 * (100+50) = $3 as the basic transaction fee.
2. Method calcBasicMileage() takes no parameter and it returns a double type.
   1. This method calculates the basic mileage award for the user by awarding 1 mile for every $20 spent.
   2. Follow the same example above, this credit card user spends $150 (domestic and foreign in total), and will receive an award of $150 / ($20 per mile) = 7.5 miles.

/** CreditCard.java */

Code a subclass named ExpressCard that inherits from the superclass CreditCard, which has two private data members:

1. foreignFeeRate of double type,
2. and domesticBonusMileageRate of double type.

Provide:

1. default constructor with no parameters,
2. constructor with all parameters to initialize its own private data and the inherited data from CreditCard
3. getter/setter methods for each data member

There are two effector methods:

1. Method calcFee() takes no parameters and it returns double type.
   1. This method calculates the transaction fee.
   2. First you need to call the method in superclass to obtain the basic fee, and then for ExpressCard user, there is an extra charge for foreign spending.
   3. Given the same example above as in class CreditCard, the basic fee is $3, and under a foreignFeeRate of 3%, then the extra fee is calculated by multiplying $50 of foreign spending with 3% (0.03) of foreignFeeRate, which yields $50 *0.03 = $1.5, so the total fee is $3 + $1.5 = $4.5.
      
2. Method calcMileage() takes no parameters and it returns double type.
   1. This method calculates the mileage award.
   2. First you need to call the method in superclass to obtain the basic mileage, then there is a bonus mileage award for domestic spending under a rate of domesticBonusMileageRate.
   3. Given the same example as in class CreditCard, the basic mileage award is 7.5 miles, and if the domesticBonusMileageRate is 4% (0.04), then the bonus mileage is calculated by multiplying $100 of domestic spending with domesticBonusMileageRate 0.04, which yields 4 miles. Then the total mileage award is 7.5 + 4 = 11.5 miles.

/** ExpressCard.java */

Code a subclass named PremiumCard that inherits from the superclass CreditCard, which has two private data members:

1. annualMemberFee of double type,
2. and foreignBonusMileageRate of double type

Provide:

1. default constructor with no parameters,
2. constructor with all parameters to initialize its own private data and the inherited data from CreditCard
3. getter/setter methods for each data member

There are two effector methods:

1. Method calcFee() takes no parameters and it returns double type.
   1. This method calculates the transaction fee.
   2. First you need to call the method in superclass to obtain the basic fee, then for PremiumCard user, the annual member fee must be added on top of the basic fee.
   3. Given the same example above as in class CreditCard, the basic fee is $3, and if the annual member fee is $65, then the total fee is $3 + $65 = $68.

2. Method calcMileage() takes no parameters and it returns double type.
   1. This method calculates the mileage award.
   2. First you need to call the method in superclass to obtain the basic mileage, then there is a bonus mileage award for foreign spending under a rate of foreignBonusMileageRate.
   3. Given the same example above as in class CreditCard, the basic mileages award is 7.5 miles, and if foreignBonusMileageRate is 20% (0.2), then the bonus mileage is calculated by multiplying $50 of foreign spending with foreignBonusMileageRate 0.2, which yields 10 miles. Then the total mileage is 7.5 + 10 = 17.5 miles.

/** PremiumCard.java */

Code a class named JohnDoeTest that has a main method. Replace JohnDoe with your name.

In the main method, create two objects:

1. one ExpressCard object,
2. and one PremuimCard object

When creating these two objects, you need to use the constructor that has all parameters in each class, and you need to hardcode reasonable values for the parameters needed by the constructor in each class. (There is no need to ask user to input data - so don’t include the Scanner class!).

Then in the main method, use each object created above to invoke the necessary methods, so that you can calculate each object’s transaction fee and mileage award, then output the transaction fee and mileage award.

Keep 2-digit precision in the output for transaction fee, and keep 1-digit precision in output for mileage award.

/** JohnDoeTest.java, and replace JohnDoe with your name*/

Please explain the steps to calculate the answer. thx!

1. Your investment has a 10% chance of earning a 30% rate of return, a 50% chance of earning a 10% rate of return and a 40% chance of losing 6%. What is your expected return on this investment?

2. Consider a T-bill with a rate of return of 5 percent and the following risky securities:
Security A: E(r) = 0.15; Variance = 0.04
Security B: E(r) = 0.10; Variance = 0.0225
Security C: E(r) = 0.12; Variance = 0.01
Security D: E(r) = 0.13; Variance = 0.0625
From which set of portfolios, formed with the T-bill and any one of the 4 risky securities, would a risk-averse investor always choose his portfolio?

3. You are considering investing $1,000 in a complete portfolio. The complete portfolio is composed of treasury bills that pay 5% and a risky portfolio, P, constructed with 2 risky securities X and Y. The optimal weights of X and Y in P are 60% and 40% respectively. X has an expected rate of return of 14% and Y has an expected rate of return of 12%. To form a complete portfolio with an expected rate of return of 11%, you should invest __________ of your complete portfolio in treasury bills.

4. Which of the following correlations coefficients will produce the least diversification benefit?

5.

The standard deviation of a portfolio consisting of 30% of Stock X and 70% of Stock Y is:

6. Stocks A and B have the following returns in each of the states given below:

The probability of the good state is 0.4, the probability of the bad state is 0.3 and the probability of the ugly state is 0.3. What is the covariance between the returns of A and B?

7. Assume that you manage a risky portfolio with an expected rate of return of 15% and a standard deviation of 30%. The T-bill rate is 10%. Suppose that you have a client that prefers to invest in your risky portfolio a proportion (y) of his total investment budget so that his overall portfolio will have an expected rate of return of 15%. What is the investment proportion y?

I am trying to make a Risk Management tool in Python. I have it partially started. The scenario is that the Project Manager needs to be able to log on and enter information ( the required information is located in the code). I then need to capture that data and store it in an array with the ability to call back and make changes if necessary. Could you please help me out and explain what was done?
