a) Explain the relationship between "programming to interfaces" and "loose coupling," why we care about these two things, and why it is not possible to create completely decoupled code.

b) Given the fact that we care about these two concepts, why might this imply that the new operator is problematic for creating flexible code?

This is the question about Verilog.

the H/W question is "Explain about 'always syntax' in verilog with the simple verilog example."

During the holiday season, shoppers were asked to estimate how much money they spent on gifts for themselves. Raw data is given below. Are the reported amounts significantly less than the actual amounts as determined from the receipts?

1) Write Ho (null) and H1 (alternative); indicate which is being tested.

2) Perform the statistical test ad write answer to the original question as a statement related to the original query

2) Construct a 99% confidence interval estimate of the mean difference between reported amounts and actual amounts . Interpret the resulting confidence interval, does it contain 0?

Learning Objectives

• Writing classes that represent objects
• Define object's state (Instance variables)
• Define objects constructors
• Write getter (accessor) and setter (mutator) methods.

As in previous labs, please write the Java code for each of the following exercises in BlueJ. For each exercise, write a comment before the code stating the exercise number.

Make sure you are using the appropriate indentation and styling conventions

Exercise 1 (15 Points)

• In BlueJ, create a new project called Lab5
• In the project create a class called DogDemo with a static method called makeDogs
• Create a second class in the same project called Dog that will represent a single dog (just a class header and an empty body for now).
• In the makeDogs method, create a Dog object called myDog. Note that the Dog and DogDemo classes are now connected by a dotted arrow in the project window to show that DogDemo depends on (uses) the Dog class.

Exercise 2 (20 Points)

• In the Dog class, create a variable at the class level (also called instance data or a field) that will represent the dog's name (a String).
• Declare this variable as private. This puts the Dog class in charge of how the name gets updated. This variable is not DIRECTLY accessible from outside the Dog class.
• In the declaration of the variable, initialize it to "Lassie".
• Create a toString method that returns the dog's name.
• In the makeDogs method of the DogDemo class, print the Dog object you created. Run the makeDogs method.

Exercise 3 (15 Points)

• This would be OK if all dogs were named Lassie!! Each instance of Dog (each Dog object) will have its own name variable, which contain different values. So create a constructor in the Dog class that accepts a parameter which is used to set the name variable.
• In the makeDogs method, create a new dog and pass in the name "Lassie" to its constructor.
• Create a second Dog object with a different name, "Rover" for example.
• Print the two dog objects.

Exercise 4 (15 Points)

• Add another field to the Dog class representing the dog's breed (a String) and one representing the dog's age (an int). Both fields should be private.
• Modify the Dog constructor to set these values as well, based on parameters.
• Define a new Dog objects in makeDogs and give them a name, breed and age.
• Modify the toString method to return a string in the following form:

Fido is a 3-year-old German Sheppard

• Test the updated makeDogs method. Think through what is happening at each step.

Exercise 5 (10 Points)

• Add standard "getter" methods for all three fields. Remember that getter methods just returns the value of a private instance variable (field). This will make the value of a private variable accessible ONLY through this method.
• In the makeDogs method, get and print just the breed of one of your created objects.
• Then get and print just the name of another one of the created objects.

Exercise 6 (10 Points)

• In Dog, add a "setter" method for the age field. Don't change the age if the parameter is less than 1.
• In the makeDogs method, try to set the age of yourDog to 0, then print the Dog object to make sure the age did not change.
• Then set the age of yourDog to 4 and print it again.

Exercise 7 (15 Points)

• You may have heard the expression "That's 21 in dog years" or something similar. The idea is to come up with a number to make it easy to compare a dog's age to that of a human in terms of overall life span. The calculation used is real age multiplied by 7. So a dog that's 3 years old is "21 in dog years".
• Add a method in Dog called getDogYears that returns the dog's age in dog-years. Do NOT create another field for this. Just return the dog's current age multiplied by 7.
• In the makeDogs method, print each dog's age in dog-years:

Rover is 28 in dog-years.

On January 1, 2016, Apple granted 80,000 stock options to key members of its executive team. Each option grants the executives the ability to purchase one share of Apples common stock ($10 par value) at a price of $40 per share. The options were exercisable within a 2-year period beginning on January 1, 2018, as long as the executives remain an employee at Apple until that date. It is assumed that the options were for services performed equally in 2016 and 2017. The Black-Scholes option pricing model determines total compensation expense to be $1,300,000. On January 1, 2018, the Apple executives exercised 48,000 of their stock options. On that date, Apples stock had a market price of $50 per share. The remaining 32,000 stock options lapsed on January 1, 2020 because of the decision not to exercise their options.

Required

1. Prepare the necessary journal entries related to the stock option plan for the years 2016 through 2020.
2. Over what period of time should compensation cost be allocated?

You are a staff associate at a major public accounting firm and graduated from college two years ago. You are working on an audit for a small, non-profit religious publishing firm. After performing tests on the royalty payables system, you discover that for the past five years, the royalty payable system has miscalculated the royalties it owes to authors for their publications. The firm owes almost $100,000 in past due royalties. All of the contracts with each author are negotiated differently. However, each author’s royalty percentage will increase at different milestones in books sold (i.e., 2% up to $10,000 and 3% thereafter). The software package did not calculate the increases, and none of the authors ever received their increase in royalty payments. At first you can’t believe that none of the authors ever realized they were owed their money. You double check your calculations and then present your findings to the senior auditor on the job.

Much to your surprise, his suggestion is to pass over this finding. He suggests that you sample new additional royalty contracts and document that you expanded your testing and found nothing wrong. The firm’s audit approach is well documented in this area and is firmly based on statistical sampling. Because you had found multiple errors in the small number of royalty contracts tested, the firm’s approach suggested testing 100% of the contracts. This would mean (1) going over the budgeted time/expense estimated to the client; (2) possibly providing a negative audit finding; and (3) confirming that the person who audited the section in the years past may not have performed procedures correctly.

Based on the prior year’s work papers, the senior auditor on the job performed the testing phase in all of these years just before his promotion. For some reason, you get the impression that the senior auditor is frustrated with you. The relationship seems strained. He is very intense, constantly checking the staff ’s progress in the hope of coming in even a half-hour under budget for a designated test/audit area. There’s a lot of pressure, and you don’t know what to do. This person is responsible for writing your review for your personnel file and bonus or promotion review. He is a very popular employee who is “on the fast track” to partnership. You don’t know whether to tell the truth and risk a poor performance review and jeopardize your future with this company, or to tell the truth, hopefully be exonerated, and be able to live with yourself by “doing the right thing” and facing consequences with a clean conscience.

1. What would you do as the staff associate in this situation? Why? What are the risks of telling the truth for you? What are the benefits? Explain.

2. What is the “right” thing to do in this situation? What is the “smart” thing to do for your job and career? What is the difference, if there is one, between the “right” and “smart” thing to do in this situation? Explain.

3. Explain what you would say to the senior auditor, your boss, in this situation if you decided to tell the truth as you know it

You spoke with your instructor and she claimed that the average number of hours that you should study has to be more than 5 hours per week which will help you achieve an above average grade on any subject. She also suggested as a practice that you can test her claim and let her know what your conclusion is. So you decided to contact your peers and gather information to conduct a hypothesis to test your instructors claim.

Questions:

1. Contact at least 15 peers (they don’t have to be from the same class) and obtain how much time they study each week.

2. If you are to conduct a hypothesis test using the data you gathered,
   1. Which test (t test or z test) do you think be appropriate and why?
      (Hint: think about whether you have the population or sample standard deviation available)

2. Is this a test on population proportion or mean?

3. Calculate the sample statistics (sample mean or sample proportion based on the information given) (1 mark)

4. Use the data set you gathered to conduct a hypothesis test to determine your instructor’s claim. Use 0.05 level of significance. Please show your work, the 5 steps as described in the textbook.

3. Construct a 95% confidence interval for the population mean number of hours. Show your work.
