1. In words, explain what is measured by each of the following: a. SS b. Variance c. Standard deviation

2. Can SS ever have a value less than zero? Explain your answer.

6. A population has a mean of m 5 80 and a standard deviation of s 5 20. a. Would a score of X 5 70 be considered an extreme value (out in the tail) in this sample? b. If the standard deviation were s 5 5, would a score of X 5 70 be considered an extreme value?

8. Calculate the mean and SS (sum of squared deviations) for each of the following samples. Based on the value for the mean, you should be able to decide which SS formula is better to use. Sample A: 1 4 8 5 Sample B: 3 0 9 4

10. For the following sample of n 5 7 scores: 8 6 5 2 6 3 5

c. Compute SS, variance, and standard deviation for the sample. (How well does your estimate compare with the actual value of s?)

13. A population has a mean of m 5 30 and a standard deviation of s 5 5. a. If 5 points were added to every score in the population, what would be the new values for the mean and standard deviation? b. If every score in the population were multiplied by 3, what would be the new values for the mean and standard deviation?

22. In an extensive study involving thousands of British children, Arden and Plomin (2006) found significantly higher variance in the intelligence scores for males than for females. Following are hypothetical data, similar to the results obtained in the study. Note that the scores are not regular IQ scores but have been standardized so that the entire sample has a mean of M 5 10 and a standard deviation of s 5 2. a. Calculate the mean and the standard deviation for the sample of n 5 8 females and for the sample of n 5 8 males. b. Based on the means and the standard deviations, describe the differences in intelligence scores for males and females. Female9,11,10,13,8,9,11,9 Male 8,10,11,12,6,10,14,9

23. Within a population, the differences that exist from one person to another are often called diversity. Researchers comparing cognitive skills for younger

adults and older adults, typically find greater differences (greater diversity) in the older population (Morse, 1993). Following are typical data showing problem-solving scores for two groups of participants.

Older Adults (average age 72) Younger Adults (average age 31)

9 4 7 3 8 7 9 6 7 8

6 2 8 4 5 6 7 6 6 8

7 5 2 6 6 9 7 8 6 9

a. Compute the mean, the variance, and the standard deviation for each group.

b. Is one group of scores noticeably more variable (more diverse) than the other?

SAMPLE ASSIGNMENT

Sample-2

PA 410

Question 1:

(4 points) You just graduated from the University of Arizona.  Unfortunately, you have also accumulated a $25,000 student loan over four years.  Now you need to start paying it off.  Suppose the interest rate on the loan is 5% and you need to pay off the loan in 10 years with equal annual payment every year.

1. What is your annual equal payment? Also draw up an amortization payment schedule of interest and principal payment every year for the 10 years. (2 points)

2. As we know, the interest on student loan, up to $2,500 each year, is deducted from your gross income to figure out your adjusted gross income (AGI). Suppose your marginal tax rate for the next ten years after graduation is 20%.  Please figure out how much this deduction can save you in federal personal income tax every year for the next 10 years. (1 point)

3. Please say in a few sentences why federal government should allow you to deduct student loan interest payment from your income to calculate your tax liability. (1 point)

Question 2:

(4 points) Suppose Pima County issued a $50 million debt to build a new jail in 2015.  The interest rate on the debt was 6%.  The original debt payment schedule was to pay off the debt in 30 years with equal annual payment every year.  After five years, the interest rate is now down to 4% in 2020.  The County wants to refinance its debt at this low rate, that is to say to issue a new debt at 4% to pay off what is left of the old debt and then make debt payment on the new debt.  If the city can issue a new debt at 4% with a maturity of 25 years beginning in 2020, please figure out:

1. What is the annual level payment on the old debt? (1 point)

2. What is the amount of the new debt to be issued in 2020? (1 point)

3. What is the saving in annual payment every year for the next 25 years? (Assume also an equal annual payment on the new debt.) (1 point)

4. Use this case as an example, briefly comment on why citizens should care about your local government debt management. (1 point)

Question 3:

(2 points) Say the city of Tucson now has an annual budget of $100 million, and by city charter, it cannot spend more than 10% of its budget on debt service, including both principal and interest payment. The city’s existing annual debt payment is $7 million. Suppose the city needs to borrow $50 million for a capital project, and the debt will be paid back over 30 years with equal annual payments.

1. If the current interest rate is 5% for a 30-year loan, can the city afford this new debt? (0.5 point) (You need to provide numbers to support your answer.)

2. Suppose the current interest rate now has dropped to 4%, can the city afford the debt now? (0.5 points) (You also need to provide numbers to support you answer.)

3. Please use this example to explain why lower long-term interest rate is desirable in the face of a weak economy. (1 point)

SAMPLE ASSIGNMENT

Sample-2

In this exercise, you will work with an excel data set that consist of information about individuals who
have applied for a loan. The information included are client identification, income, age, loan amount
they have applied for, and whether or not they have defaulted with a loan payment in the last 10 years.
The process you go through and your final output is supposed to help you create a model that would be
able to identify individuals who are most likely to pose a credit risk to the loan company.
We will use the RapidMiner Data mining software. Make sure you install the correct version of
RpaidMiner Studio on your laptop. Choose either a 32 bit or a 64 bit based on the specifications of the
operating system on your computer. Include as many screenshot (of relevant steps) as possible.
Particularly, you would use the Decision tree algorithm in the RapidMiner Machin learning software to
build a model.

Draw an ERD for each of the following situations. (If you believe that you need to make additional
assumptions, clearly state them for each situation.) Draw the same situation using the tool you have
been told to use in the course.
1. A company has a number of employees. The attributes of EMPLOYEE include
Employee ID (identifier), Name, Address, and Birthdate. The company also has several
projects. Attributes of PROJECT include Project ID (identifier), Project Name, and Start
Date. Each employee may be assigned to one or more projects, or may not be assigned
to a project. A project must have at least one employee assigned and may have any
number of employees assigned. An employee’s billing rate may vary by project, and the
company wishes to record the applicable billing rate (Billing Rate) for each employee
when assigned to a particular project.
2. A laboratory has several chemists who work on one or more projects. Chemists also
may use certain kinds of equipment on each project. Attributes of CHEMIST include
Employee ID (identifier), Name, and Phone No. Attributes of PROJECT include Project
ID (identifier) and Start Date. Attributes of EQUIPMENT include Serial No and Cost. The
organization wishes to record Assign Date—that is, the date when a given equipment
item was assigned to a particular chemist working on a specified project. A chemist must
be assigned to at least one project and one equipment item. A given equipment item
need not be assigned, and a given project need not be assigned either a chemist or an
equipment item.
3. A college course may have one or more scheduled sections, or may not have a
scheduled section. Attributes of COURSE include Course ID, Course Name, and Units.
Attributes of SECTION include Section Number and Semester ID. Semester ID is
composed of two parts: Semester and Year. Section Number is an integer (such as 1 or
2) that distinguishes one section from another for the same course but does not uniquely
identify a section.
4. A hospital has a large number of registered physicians. Attributes of PHYSICIAN include
Physician ID (the identifier) and Specialty. Patients are admitted to the hospital by
physicians. Attributes of PATIENT include Patient ID (the identifier) and Patient Name.
Any patient who is admitted must have exactly one admitting physician. A physician may
optionally admit any number of patients. Once admitted, a given patient must be treated
by at least one physician. A particular physician may treat any number of patients, or
may not treat any patients. Whenever a patient is treated by a physician, the hospital
wishes to record the details of the treatment (Treatment Detail). Components of
Treatment Detail include Date, Time, and Results.
5. The loan office in a bank receives from various parties requests to investigate the credit
status of a customer. Each credit request is identified by a Request ID and is described
by a Request Date and Requesting Party Name. The loan office also received results of
credit checks. A credit check is identified by a Credit Check ID and is described by the
Credit Check Date and the Credit Rating. The loan office matches credit requests with
credit check results. A credit request may be recorded before its result arrives; a
particular credit result may be used in support of several credit requests.
6. An art museum owns a large volume of works of art. Each work of art is described by an
item code (identifier), title, type, and size; size is further composed of height, width, and
weight. A work of art is developed by an artist, but the artist for some works is unknown.
An artist is described by an artist ID (identifier), name, date of birth, and date of death
(which is null for still living artists). Only data about artists for works currently owned by
the museum are kept in the database. At any point in time, a work of art is either on
display at the museum, held in storage, away from the museum as part of a traveling
show, or on loan to another gallery. If on display at the museum, a work of art is also
described by its location within the museum. A traveling show is described by a show ID
(identifier), the city in which the show is currently appearing, and the start and end dates
of the show. Many of the museum works may be part of a given show, and only active
shows with at least one museum work of art need be represented in the database.
Finally, another gallery is described by a gallery ID (identifier), name, and city. The
museum wants to retain a complete history of loaning a work of art to other galleries,
and each time a work is loaned, the museum wants to know the date the work was
loaned and the date it was returned.
7. Each case handled by the law firm of Dewey, Cheetim, and Howe has a unique case
number; a date opened, date closed, and judgment description are also kept on each
case. A case is brought by one or more plaintiffs, and the same plaintiff may be involved
in many cases. A plaintiff has a requested judgment characteristic. A case is against one
or more defendants, and the same defendant may be involved in many cases. A plaintiff
or defendant may be a person or an organization. Over time, the same person or
organization may be a defendant or a plaintiff in cases. In either situation, such legal
entities are identified by an entity number, and other attributes are name and net worth.
8. Each publisher has a unique name; a mailing address and telephone number are also
kept on each publisher. A publisher publishes one or more books; a book is published by
exactly one publisher. A book is identified by its ISBN, and other attributes are title, price,
and number of pages. Each book is written by one or more authors; an author writes one
or more books, potentially for different publishers. Each author is uniquely described by
an author ID, and we know each author’s name and address. Each author is paid a
certain royalty rate on each book he or she authors, which potentially varies for each
book and for each author. An author receives a separate royalty check for each book he
or she writes. Each check is identified by its check number, and we also keep track of
the date and amount of each check.
