Part One
• Confidence Interval
Commonly used confidence levels are 90%, 95%, and 99% To compute the 95% confidence interval, start by computing the mean and standard error:
M = (2 + 3 + 5 + 6 + 9)/5 = 5. σM = = 1.118.
• Bell Shaped Curve
The mean is inside the confidence interval level.
Part Two
• H0: Null hypothesis (no change, no difference); H1: Alternative Hypothesis; α =0.05
The critical value t 0.05,14 is 1.789. the observed test statistic is the Z value on the that leads to a probability of 83/100 or .83
• Bell Curve with critical test statistics
• The observed test statistic is in the critical region
• The p value is greater than the alpha.
Part Three
• H0: Null hypothesis is µ= 100 ; H1: Alternative
Tragedy impacts each human being differently. Some are able to forgive and forget, some become angry and seek vengeance of some sort, while others bury those feelings deep within themselves and become apathetic. In The Assault by Harry Mulisch uses careful diction, apprehensive tone, striking oxymoron, and dark irony to show that while many may have been involved in the same tragedy, their roles in the tragedy and how they handle grief from it create a different outcome for each.

He remembers appreciating nature, encountering and writing to Becky, the first time he’d shot a gun, and Christmas leave. Luke identifies the moment when he realizes that he had joined the army for the wrong reason, after crossing the bridge his team built in order to cross the valley, and at the same time dreading the return to his former office job. Boredom and nothingness destroy him mentally as he waits for enemies to appear. When the enemies finally appear, he shoots them down and goes home the next day. Sayrafiezadeh proposes that expectations don’t always equate
Equality is not something we get to have when we come into this world. It is something that is being fought for and will continue to fight for as long as people think of themselves and do not think of the consequences that may occur from their own actions.

The different examples of injustices that were occurring around the countries. Lastly explains the ways the oppressed used there actions, words, and ideas to fight the injustices. Injustices are all around world many of which still have a lot of control to this day and take a toll on the less able. Allowing large corporations to dictate what will be said and done.
The Andes had a legacy of resistance that was unseen in other Spanish occupied place during the colonial period. There were rebellions of various kinds as a continued resistance to conquest.

The Letters of Insurrection displays effects of colonization and how the “lesser-known” revolutionaries that lived in reducción towns played a role in weakening colonial powers and creating a place of identification for indigenous people.
Answer: The fact that an investigation of local restaurants was conducted in which 150 were selected randomly indicates that this is a sample. This sample indicates that out of the 150 randomly selected, 42% of this random selection out of the total population of restaurants possessed series health code violations.
The question for our research will be very relevant to our statistical test, therefore, the question will be: Is there going to be any significant dissimilarity amongst quiz 3 in different sections of our data set? Then the null hypothesis question is: Are there (no) any difference in the Quiz 3 by the sections. Then our alternative hypothesis will be the quiz 3 by the section. Therefore, we will have an alpha level of 5%.
What exactly does it take to create a successful leading retail store? So many companies are in competition of gaining the shopper’s loyalty they end up neglecting other important aspects. A perfect retailer has to balance out high-quality, attractive prices, customer loyalty, and an enjoyable environment. “Target has experienced considerable growth in the last decade because its stores offer fashionable merchandise at low prices in a pleasant shopping environment.” (pg42) “It has developed an image of ‘cheap chic’.” (pg42)
Deviance is a natural part of and necessary for stability and social order in society, this according to functionalist theorist Emile Durkheim (MindEdge, Inc., 2016). Traditionally, society is generally successful in providing motivation for individuals to aspire for goals of some sort, whether through wealth, prestige or perceived power (Henslin, 2011). However, from a functional perspective, theories have been developed in identifying when lawful and equal access is not afforded to certain individuals in the process of obtaining such goals. This restriction and inequality to opportunity for access in the quest to achieve success is what is now referred to as structural strain theory, which was developed by sociologist Robert Merton (Henslin,

Once the team has assembled and once the SITSA has completed the formalities associated with communicating to company leaders and stakeholders, the next stage is to begin assessing and analyzing the attack. Brandon (2014) provides the following guidelines for security analysts and those charged with evaluating the attack in terms of its specific dimensions. These include the processes of isolating the impacted networking components; protecting critical infrastructures against further compromise; detecting the source of the intrusion; analyzing the components and signatures associated with it; and making clear assessments based on this aggregate data. In total, this effort can be viewed as a strategy that analyzes an attack in terms of its technical aspects and the likely qualitative aspects connected with the attacker.
When asking the average citizen about Afghanistan, most would regurgitate facts they have heard about the United States invading for several years because of the war on terrorism. There was and is still much more to the war in Afghanistan then what you see and here in the news. Although most troops are out, the war is far from over. Being a citizen in Afghanistan is not an easy task. Everyday you are faced with an almost non-existent government and the utter chaos of warlords throughout the country. Women are raped, children are harassed, and citizens are killed daily. Warlords have been in control of Afghanistan for several years now and will continue their reign of terror unless it is put to an end. The research conducted in
