...How many standard deviations is my hypothesis (sample mean) is away from the actual (null hypothesis population mean)
T – statistic
Rejecting the null may be a mistake = p –value
ONE SAMPLE
3 formulas
T.Dist.rt (t, sample size - 1 “df”) -> alternative that mu is bigger than a
1 – T.Dist.rt (t, sample size – 1) -> mu is less than a
T.Dist.2t(t,samplesize - 1) -> not equal to
p < significant level reject the null
NEVER accept null
TWO SAMPLE
directly get the p-value
chance that under the null hypthoesis, you have a difference in the sample mean that is as extreme or more as what you have now. If that probability is small, it is something in the nature not due to chance.
* Paired: T.Test (sample 1, sample 2, # of tails , 1)
* not equal to: number of tails = 2
* greater than or less than: number of tails = 1
* Type 1 = paired data (ex: every UNC mba student’s salary before they entered the program and salaries after graduate )
* salaries have a significant increase after mba?
*
* Independent: T.Test (sample 1, sample 2, # tails, 2)
* Type 2 = independent (ex: UNC mbas vs. DUKE mbas)

1) What sets an experiment aside from the rest?
-random assignment
-manipulation
-controlling for confounds
-causal relationship
2) independent variable: variable that gets manipulated/controlled.
3) within subject: everybody gets exposed to all levels (treatment); experiment with a few individuals; Designed to study “laws” of behavior; Historically significant
4) between subjects: diff groups assigned to diff levels (control)
5) order effects: (testing effects): problem in within subject design; occur when participants are tested more than once in a study with early testing affecting later testing.
6) counterbalancing (combats testing effects): change the order; controlling for the effects of an extraneous variable by ensuring that its effects are equal in all treatment conditions. For example, order effects can be counterbalanced by administering the various procedures in different sequences.
7) systematic root differences (a problem in between subject designs)
8) match design (contains random assignment; combats systematic root differences): participants are grouped through the coupling of participants from similar attributes such as age, height, interests etc. used when there is an extraneous variable that the experimenter thinks might be related to the dependent variable … and the experimenter wants to be sure it does not become a confounding...

What is the difference between published and assigned software?
Typically, after you publish a software package to users in a site, domain, or OU, the users can use Add or Remove Programs to install the software. After you assign a software package to users in a site, domain, or OU, the software is advertised on the desktop. The application becomes available to the user the next time the user logs on (if application’s GPO applies to that user). The application is fully installed by the user from the Start menu, from Add or Remove Programs, from a desktop shortcut, or by opening a document (on demand) that has a file name extension that is associated with the application.
To backup active directory what feature do you install?
Install the backup features from the Server Manager.
What’s the name of the process to manually defrag active directory database?
SAM: Security Accounts Manager
What is a starter GPO?
A Starter GPO can be thought of as a Group Policy Object (GPO) template that may administrators use as a baseline while creating any new GPO.
Know the different tabs within the group policy management console: scope, details, settings and delegations and what they do.
What is the difference between MSI and MST?
When deploying software in a client server environment with either group policy or System Management Server, you are required to use an MSI file for the deployment. A MST file is a transform...

...1. (5 pts)What is the Hecksher-Ohlin Theory of Comparative Advantage?
This is a theory developed by two Swedish economists to explain how countries develop comparative advantage in certain areas rather than others.
The model works as follows:
1) Assume every country, for the most part, has access to the same technology.
2) Still, factors of production are difficult to move across national boundaries.
3) It follows from (2) that factors of production are relatively bound by geography and national borders, and that not every country can obtain the proportions need to maximize production.
4) Because the amount of productive resources differs between each country, it follows that countries will have comparative advantages in products that are intensive in factors that they have an abundance of.
(5 pts) Apply this model to explain trade between Great Britain and the United States in mid-nineteenth century.
Applying the model to U.S.-Great Britain trade:
1) Great Britain had a relative abundance of labor and scarcity of land.
2) The U.S. had an abundance of land and scarcity of labor.
3) Great Britain should develop a comparative advantage in sectors that were labor intensive and not very land-using such as factory production, cotton, and ironworking.
4) The U.S. should develop a comparative advantage in goods that require lots of land but little labor, such as wheat and corn.
5) Great Britain and the U.S. did develop comparative advantage in their expected areas,...

...FinalExamReview Sheet Philosophy 110, Fall Term 2006
The finalexam will take place Thursday, December 21st, in the usual classroom from 4:30-7pm. It will consist of around 15 true/false or multiple choice questions, and a dozen or so short answer questions. The exam will be comprehensive – that is, it will cover material from the entire semester. The emphasis will be on material we have studied since the last exam—probably one-half to two-thirds of the finalexam will cover this new material. But note that that still means one-third to one-half of the exam will cover material from the previous two exams.
The following are important concepts, positions, objections, arguments, etc., that we have covered since the last exam. Review these, and take a look at the previous two examreviews as well.

CH 9: Quantitative Research Design p. 201-235
• Random numbers tables (how are they used in research) p.207
o Researchers can use a table of random numbers to randomize. A small portion of such a table is shown in Table 9.2. In a table of random numbers, any digit from 0 to 9 is equally likely to follow any other digit.
• Types of research designs:
1. Cohort: A non-experimental design in which a deﬁned group of people (a cohort) is followed overtime to study outcomes for subsets of the cohorts; also called a prospective design. P. 234 prospective (cohort) designs (studies that begin with a presumed cause and look forward in time for its effect.
2. Randomized controlled (trial): A full experimental test of an intervention, involving random assignment to treatment groups; sometimes, phase III of a full clinical trial.
Experiments (or randomized controlled trials [RCTs]) involve manipulation (the researcher manipulates the independent variable by introducing a treatment or intervention); control (including use of a control group that is not given the intervention and represents the comparative counterfactual); and randomization or random assignment (with people allocated to experimental and control groups at random to form groups that are comparable at the outset). P. 232
