1. A key point to get out of this topic is the idea that these
errors are theoretical. You won't be sure as to whether one
occurred or not. Why are they theoretical in nature? Hint: think
about a study and knowing the "truth"
2. Pick a study of interest and identify the null and alternative
hypothesis. How does this fit in with regards to the topic of a
type I and type II error? Always keep this in mind when you are
trying to identify what a type I and type II error are.

topic
1) According to the reading, we set the alpha which is the
largest probability for type I error. To increase the power of a
hypothesis researchers can use larger samples which provides
more information and raise the significance level which
increases the probability that the hypothesis will be rejected.
2) A Type 1 error occurs when individuals involved in research
make the decision to reject the belief of truth when in actuality
the hypothesis is true. Type 1 errors are errors in research when
the researcher makes the wrong decision to reject a true null
hypothesis. Type II errors are considered less of a problem than
Type 1 errors, but can prove to be detrimental in the field of
medicine. This type of error occurs when researchers decide to
keep a false null hypothesis, when in fact the hypothesis is true.
The method to avoid making Type 1 decisions is to test the null

hypothesis at the highest level (Alpha Level). This will lessen
the possibilities of making this type of error (Privitera, 2018).
3) According to Privitera (2018) a type 1 error is the probability
of rejecting a null hypotheses that is actually true, researchers
purposely make this error. A null hypotheses is a statement
about a population parameter that is assumed to be true, this
hypotheses is a starting point (Privitera, 2018). The type 2 error
or beta error is the probability of retaining a null hypotheses
that is actually false (Privitera, 2018). The type 1 error is
committed when a researcher decides to reject previous notions
of truth that are in fact true (Privitera, 2018). The best way to
avoid these types of errors is to be open minded and not reject
notions if there is fact to back the notions up. In my opinion a
type 1 error is something committed with bias by the researcher.
I say this because as a researcher it is their job to find all facts
or at least most all facts and apply them to their study or
research, especially if they commit a type one error knowingly.
If a researcher does this error then they are not following
through with basic research guidelines.
4) A one-tailed test is used in a hypothesis test where the
alternative hypothesis is stated as either (>) or (<). When a
researcher is interested in a specific alternative to the null
hypothesis. A two-tailed test is used when one wants to avoid
making a type III error. An error that occurs when one accepts a
null hypothesis that is incorrect because the the rejection region
of the tail was on the opposite end. SPSS can be used to
compute the calculations for each by imputing data in to a new
data chart and then using the frequencies tab to help solve for
the mean and standard deviation. From there one can use
appendix c. to solve for the two-tails. (Privitera., G. J., 2018).
5) We use the one-tailed test when we need to check or test the
claim or hypothesis which is directional in nature. This means if
the alternative hypothesis of the test includes ‘less than’ or
‘greater than’, then we use one-tailed tests. We use the two-
tailed test when we need to check or test the claim or hypothesis
which is non-directional in nature (Privitera., G. J., 2018). That

is, if the alternative hypothesis of the test includes ‘not equal
to’, then we use two-tailed tests. When we perform one-tailed
tests and two-tailed test by using SPSS, then we need to use
some setting or calculations. For most of the tests, SPSS
provides the results for the two-tailed test as a default. Most of
the times, SPSS do not provide results for one-tailed tests and
in such cases, we need to calculate the p-value from this output.
Examples of one tailed and two tailed test is given as below:
H0: µ = 10 v/s Ha: µ < 10 (One tailed /lower tailed /left tailed
/directional test)
H0: µ = 10 v/s Ha: µ > 10 (One tailed /upper tailed /right tailed
/directional test)
H0: µ = 10 v/s Ha: µ ≠ 10 (two tailed /non-directional test)
6) In the Type 1 error and Type 2 error, in this two types of
errors that exist in a hypothesis testing of Type 1 and Type 2.
In Type 1 and Type 2 that occur in when the null hypothesis is
true but is still being rejected. In being able to use the
following example from a law case, this is equivalent of
convicting an innocent man or individual. In the statistics or
research types of errors in types think that he or she has a
significant difference, when there is actually no significant
differences in the types of errors. A Type 2 error occurs when
null hypothesis is false but not rejected, which is equivalent of
acquiring a guilty man or individual. This is where the
researchers actually has a significant difference but does not
realize it. Many examples are generated in the Type 1 and Type
2 that allows the researcher to understand and generate this
hypothesis. In the law, example that is a matter of opinion and
often depends on the nature of the time and associated in the
factor that generates the punishment for the individual that
committed the crime. That is why it is important to understand
the meaning, understanding and hypothesis of this type 1 and
type 2 significant of errors. In the statistics, replication of
studies will reduce the chance that an artifact appears
significant when it is not. In one type of error is eliminated and

there is a very good chance of the other occurring. In the
chance of both types of errors cannot be eliminated. There are
many factors that allows the reseacher to come up with this type
of hypothesis that allows them too see and understand this type
1 and type 2 errors.
7) After researching and exploring this question, it is my belief
that if you can explain why you are more interested in an effect
in one direction and not the other direction, it is a good time to
use a one-tailed test. A plus is an improvement in power to
reject the null hypothesis if the null hypothesis is definitely
false. A more extensive null hypothesis with the ability to
detect unexpected results can be restricted when the null
hypothesis is not rejected. There is a higher level of trust; the
lower the level p-value the less plausible that the null
hypothesis is true. The one-tailed test is used where an
alternative hypothesis is more or less whereas a two-tailed test
is used when the researcher is attempting to avoid a type III
error. According to Privitera (2018), A basic explanation of how
SPSS is used to perform the calculations is to : go to the
analysis menu; compare means from drop down menu click one
sample t test from pop-up menu select the dependent variables
you want to test check arrow button to move variables into test
variables pain test box enter value compare to click ok etc.
imputing the data use frequencies tab will find the mean and
standard deviation. The two-tailed test can be found using
appendix c

Assignment 3: Design with UML
Advanced Business Systems (ABS) is a consulting and staffing
company providing specialized staffing and consulting services
to clients in a variety of different industries. It has offices in
major U.S. metro areas and has ongoing relationships with
Fortune 500 companies. Its areas of services range from
software development and network engineering to geo-
information systems. It has fifty (50) plus regional offices in
U.S. and five (5) offices in Canada. It plans to expand to other
countries in the future.
When an ABS client company determines that it will need a
contractor or temporary professional, it issues a staffing request
against the contract it had previously negotiated with ABS. The
contract manager in ABS reviews the staff request and ensures
that the request is valid with its current contract with its client

from the database.
· If the request is not valid, the contract manager sends the
staffing request back to the client and explains the reasons and
asks for the need for starting a new contract.
· If the request is valid, the contract manager will start
recruiting requests by putting the request into its staffing
database. The staffing request is then sent to ABS placement
department.
In the placement department, the placement specialists will
check the job requirements and candidates qualifications.
· If there is a qualified candidate, the specialist will notify the
candidate and put a note in the database.
· If a qualified candidate cannot be found or not immediately
available, the specialist notifies contract managers and
recruiting department; the recruiting department starts search
outside immediately.
The recruiting department normally has thirty (30) days to find
an outside candidate and send the qualified candidates to the
placement department to review. If an internal qualified
candidate is confirmed with his / her availability, the
confirmation will be sent to the arrangement department. In the
arrangement department, the candidate works with the
specialists to further confirm the placement details, such as
starting date, location, compensation (e.g., per diem), and travel
arrangement. The final confirmation will be sent to the client
along with a billing schedule. If the client agrees with the
arrangement, he/she acknowledges the arrangement with
contract managers in the contract department. The contract
manager then puts a memo into its database and closes the
request.
Note: You may create and / or assume all necessary assumptions
needed for the completion of this assignment.
Write a three to four (3-4) page paper in which you:
1. Create a package diagram of the problem domain layer using
the communication diagrams and the CRUDE matrix through the
use of graphical tools in Microsoft Word or Visio, or an open

source alternative such as Dia. Note: The graphically depicted
solution is not included in the required page length.
2. Perform and explain the verification and validation walk-
through of the package diagram.
3. Create a set of invariants for attributes and relationships and
add them to the CRC cards for each class in the structural model
using Object Constraint Language (OCL).
4. List the classes in the structure model. Choose one (1) class
and create a contract for each method in that class. Note: Be
sure to use OCL to specify the preconditions and the post
conditions.
5. Create a method specification for each method using both
structured English and activity diagram for the algorithm
specification through the use of graphical tools in Microsoft
Word or Visio, or an open source alternative such as Dia. Note:
The graphically depicted solution is not included in the required
page length.

"Data Breach Notification" Please respond to the following:
Data breach laws have made us more aware of how our PII and
other corporate data is compromised in recent years.
Intellectual property is often the target of attacks from foreign
entities and even governments. Banks don’t like people to
know how much money is stolen annually by hackers; despite
their best efforts to prevent such theft. Discuss your thoughts
on the subjects mentioned here based on your learning from this
week.

"Online Contracts" Please respond to the following:
Online contracts are becoming ubiquitous these days. They’re
sometimes signed online even in face-to-face meetings between
parties. Based on your study this week, what are some pitfalls
you previously didn’t know? Describe an online contract or
end-user license agreement you signed that made you think. Do
you ever agree to things without fully reading them, even when
the signature block says, “I have read and understand”? What
do you think about this now that you have learned about online

contracts?
