Goal: in this lab, you will learn to configure sudo to allow a user mrussell to change
password for users. Please follow the steps and answer all the questions at the end of
the lab instruction.

In the Linux machine

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. For this part you will need a 2nd normal user (non-root) account. If you don't have
an account for "auser" with password “room1202” yet, you can create one by
running (as room1202):
$ sudo useradd -c "A User" auser
$ sudo passwd auser
2. Login as room1202, run the $ sudo visudo to edit the configuration file for sudo
to allow a normal user account (mrussell is used below) to change passwords for
users. The new entry should look like this (tab key as column dilimeter):
mrussell ALL = /usr/bin/passwd
3. Login as mrussell. What happened, if you use passwd to try to lock the account
for auser as follows:
$ passwd -l auser
4. Now try it again using sudo. This is done by running the command as normal
but with the word sudo in front:
$ sudo passwd -l auser
What output did you see from sudo? Did you lock the account this time? (Check
with sudo passwd -S auser.)
5. Try to unlock the account without using sudo:
$ passwd -u auser
What output did you see this time? Is the account unlocked now?
6. Unlock the account using sudo. What happened this time?
7. Using what you have learned about finding and reading system documentation,
enable the user mrussell to run the following command
$ sudo sudoedit /etc/hosts
Questions:
1. What file does the command visudo actually edit? (20pts.)
2. Compare the outputs from step#3 with those from step#4. What caused the
difference? (20pts.)
3. What output did you see in step#5? Then run sudo passwd –S auser and descript
what you see. (20pts.)
4. What output did you see in step#6? Then run sudo passwd –S auser and descript
what you see. (20pts.)
5. Save a screenshot in your report to prove that, on your system, you have
successfully completed step 7. (20pts.)

Scenario/Summary

We are all may be here for a different reason - some of us need the general education requirement, some are fulfilling a program requirement, and some may find the material interesting! Either way, I'm sure that we all come into this class with a preconceived view about the field of psychology.

So...what do you think?  Are psychologists just those bearded, white-haired old timers who nod at your every word while judging everything you say!? Do you have a preconceived notion of what this field is all about? Here are a few questions to get you discussing your thoughts about the field.

A. What comes to mind when thinking about the field of psychology?

B. What names come to mind when thinking of the field?

C. What do you think psychologists do? After you state what you think they do, find out what they really do (either cite our text or look online at apa.org). In other words, do your expectations match reality? Also, include an area that surprised you in your reading - what made you say: "wow, I didn't know they did this!"

2.

As our text describes, the history of psychology is full of great discoveries and advances. Our history is also marred with a number of unethical approaches to observing and assessing human behavior. For this discussion post I would like you to choose one study (for example you could choose; Henrietta Lacks or the Tuskegee experiment) that demonstrated an unethical approach to studying the mind and behavior and or human body.   

Be sure to:

(A). What happened in the study - give details of the timeline, the population studied, and what was done.  

(B). Name at least 2 ways in which this study was unethical and what underlining ethical principle(s) were violated.  

(C). In what ways could this study have been completed ethically? In other words, could anything have been changed to study the same objectives in an ethical way?

(D). What's your take on this study? How did you react when reading about it? What do you think lead the researchers to conduct such a study?

Use the Chi-Square option in the Nonparametric Tests menu to answer the questions based on the following scenario. (Assume a level of significance of .05 and use information from the scenario to determine the expected frequencies for each category).

Scenario: During the analysis of the district data, it was determined that one high school had substantially higher Graduate Exit Exam scores than the state average and the averages of high schools in the surrounding districts. To better understand possible reasons for this difference, the superintendent conducted several analyses. One analysis examined the population of students who completed the exam. Specifically, the superintendent wanted to know if the distribution of special education, regular education, and gifted/talented test takers from the local high school differed from the statewide distribution. The obtained data are provided below. Description Special Education* Regular Education Gifted/Talented Number of students from the local high school who took the

*For purposes of testing, special education includes any student who received accommodations during the exam.

1. If the student distribution for the local high school did not differ from the state, what would be the expected percentage of students in each category?

2. What were the actual percentages of local high school students in each category? (Report final answer to two decimal places)

3. State an appropriate null hypothesis for this analysis.

4. What is the value of the chi-square statistic?

5. What are the reported degrees of freedom?

6. What is the reported level of significance?

7. Based on the results of the one-sample chi-square test, was the population of test taking students at the local high school statistically significantly different from the statewide population?

8. Present the results as they might appear in an article. This must include a table and narrative statement that reports and interprets the results of the analysis.

Note: The table must be created using your word processing program. Tables that are copied and pasted from SPSS are not acceptable.

VideoDev Ltd is a video and production development company which works for clients across Australia and New Zealand. The company is considering moving some of its computer infrastructure into the Cloud. The VideoDev Board is contemplating this move as a way to increase the company’s flexibility and responsiveness, as well as to achieve some savings on the cost of maintaining their ICT infrastructure.

VideoDev has engaged you as a consultant to advise them on the use of Cloud Computing in their daily operations. They have some 100 video production, engineering and support staff that work on different projects for clients in Australia and New Zealand. They have been advised that a move to using a Cloud based infrastructure would be an advantage to them.

VideoDev have a number of application servers in their Sydney and Melbourne datacentres that provide video processing capabilities for their staff. These servers are quite heavily customised and run reasonably heavy workloads while doing video processing. There is often a considerable queue of jobs waiting to be processed, which causes backlogs in getting jobs completed on time. The Board hopes that a move to a cloud based operation may help to relieve these backlogs.   

Another of VideoDev’s initial projects is to provide all their staff with a Standard Desktop Operating Environment (SDOE) on their desktop. This would include providing a standard desktop to any device that their staff may be using, as well as access to office automation, such as email, word processing, spreadsheet capabilities, as well as online storage for their files. The Board want the SDOE to be available on any device that their staff use, whether they are in the office, at home, or deployed at a customer’s office in the field.

VideoDev is considering the use of either Amazon WorkSpaces (https://aws.amazon.com/workspaces/) or Windows Virtual Desktop (https://azure.microsoft.com/en-au/services/virtual-desktop/) as a replacement for their existing desktop environment.

1. Explain how you think that VideoDev could move their video processing to the cloud. You will need to discuss:
a. Explain the differences between the service models IaaS and PaaS
b. What type of service model you would recommend?
c. What are the advantages of, and the issues with, the service model that you recommended for VideoDev’s video processing?
d. What other types of architectural patterns could be used in this deployment?
e. How that move would assist in removing backlogs?

Project Details

John and Jane Doe are newlyweds with executive track careers at ACME Gadget Company. In five years, the Does would like to have a family, envisioning two young children, Jack and Jill. With an eye for the future, John and Jane are now looking to ensure that their future family has a place to call home, that their future children will have access to all the education they desire, and that they themselves will be able to enjoy retirement when the time comes. As such, they’ve come to your financial planning company for advice for purchasing a house, planning for retirement, setting up a RESP and for your perspective on a side venture. They’ve provided you with the background and questions below.

Purchase of a new home

John and Jane had planned to save $60 000 dollars over the next five years as a down payment on a house. Jane assured John that if they contributed $1000 each month to a savings account that pays an annual rate of interest of 2.5% compounded monthly that they would have enough money to put a down payment of $60 000 on their new house. Wanting their daughter to have a house, Jane’s parents (The Henrys) have offered to lend John and Jane $65 000, which they have suggested (perhaps naively) John and Jane pay back by contributing to a savings account in the Henrys’ name as per Jane’s original savings plan. John’s worried this is not fair to his in-laws. Is he correct? If so, devise a fair repayment plan that would see the Henrys repaid at a rate of 2.5% compounded monthly over the 5 years.

The Does have qualified for a mortgage of $500,000 to be amortized over 25 years. Their mortgage broker has offered them the following options:

1. A 5 year fixed rate with monthly payments at an annual interest rate of prime+1%
2. A 10 year fixed rate with biweekly payments at an annual interest rate of prime+2%

Prime is currently at 1.5% and projected to increase by 0.25% every year for the next 10 years. Which Mortgage terms should they accept given that their goal is to pay as much principle as possible over the next 10 years?

Please include diagram and complete on Microsoft word thank you.
