Objective: To use the statistical data/analysis provided by Fliege & Associates, to make an informed decision in determining which type of property (business) I should have built on recently inherited land in Riverside County California. I will use the descriptive statistical analysis report given on the demographical information for the county, in regards to its population of residents; to compare and contrast to a recent case study involving a similar tract of land in a likewise small community located approximately one hour away in San Diego California.

REFLECTION
The first thing that puffs in my mind when I heard the word STATISTIC is that it was a very hard subject because it is another branch of mathematics that will make my head or brain bleed of thinking of how I will handle it. I have learned that statistic is a branch of mathematics concerned with the study of information that is expressed in numbers, for example information about the number of times something happens. As I examined on what the statement says, the phrase “number of times something happens” really caught my attention because my subconscious says “here we go again the non-stop solving, analyzing of problems” and I was right. This course of basic statistic has provided me with the analytical skills to crunch numerical data and to make inference from it. At first I thought that I will be alright all along with this subject but it seems that just some part of it maybe it is because I don’t pay much of my attention to it but I have learned many things. I have learned my lesson.
During our every session in this subject before having our midterm examination I really had hard and bad times in coping up with this subject. When we have our very first quiz I thought that I would fail it but it did not happen but after that, my next quizzes I have taken I failed. I was always feeling down when in every quiz I failed because even though I don’t like this...

...techniques.
Firstly we look at data analysis. This approach starts with data that are manipulated or processed
into information that is valuable to decision making. The processing and manipulation of raw
data into meaningful information are the heart of data analysis. Data analysis includes data
description, data inference, the search for relationships in data and dealing with uncertainty
which in turn includes measuring uncertainty and modelling uncertainty explicitly.
In addition to data analysis, other decision making techniques are discussed. These techniques
include decision analysis, project scheduling and network models.
Chapter 1 illustrates a number of ways to summarise the information in data sets, also known as
descriptive statistics. It includes graphical and tabular summaries, as well as summary measures
such as means, medians and standard deviations.
Uncertainty is a key aspect of most business problems. To deal with uncertainty, we need a basic
understanding of probability. Chapter 2 covers basic rules of probability and in Chapter 3 we
discuss the important concept of probability distributions in some generality.
In Chapter 4 we discuss statistical inference (estimation), where the basic problem is to estimate
one or more characteristics of a population. Since it is too expensive to obtain the population
information, we instead select a sample from the population and then use the information in the
sample to infer the...

Question 1
The sampling method that Mr. Kwok is using is Stratified Random Sampling Method. In this case study, Mr Kwok collected a random sample of 1000 flights and proportions of three routes in the sample. He divides them into different sub-groups such as satisfaction, refreshments and departure time and then selects proportionally to highlight specific subgroup within the population. The reasons why Mr Kwok used this sampling method are that the cost per observation in the survey may be reduced and it also enables to increase the accuracy at a given cost.

...compliments the regular mathematics and therefore both are tested in primary schools. Mathematics is the written application of operation. It teaches students to think clearly, reason well and strategize effectively. Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance.
The Standard 3 class is where the transition from junior to senior level occurs where teachers expect the transference of concrete to abstract thinking would have occurred.
A common theory by many primary school teachers is ‘Students perform better in Mathematics than Mental math. Mental math is something that has to be developed and involves critical thinking. Mental math requires quick thinking and the student must solve the problem in their minds whereas in regular mathematics, the problem can be solved visually. Therefore, teachers should take these factors into consideration while testing and marking students in these areas.’
In this study, the statistics of 30 students of a standard 3 class of San Fernando Boys’ Government School will be analysed to determine the truth of this theory.

Based on the information provided in the Hamilton County Judges’ case study, the probability of cases being appealed and reversed in the three different courts are: a. For the total cases disposed in the Common Pleas Court there is a 0.1129 probability of a case being appealed and reversed. b. For the total cases disposed in the Domestic Relations Court there is a 0.1604 probability of a case being appealed and reversed. c. For the total cases disposed in the Municipal Court there is a 0.2080 probability of a case being appealed and reversed. 2. The probability of a case being appealed, per judge, is: a.

...A1. Community Description
Box Elder County is located at the north end of the Great Salt Lake in northern Utah, and extends west to the Nevada border and north to the Idaho border. The majority of the county runs along the Wasatch front, and covers a total area of 6, 729 square miles. A good portion of the county’s residents live in the rural parts of the county. Most housing units are in surrounding areas to the larger cities. The population in 2010 was estimated at 50,171. The majority of people that live in Box Elder are white. There is also a large portion that is affiliated with a religion, and vote republican during presidential elections. There does not appear to be a high poverty level, and most Box Elder County residents have obtained a high school diploma or higher.
The neighborhood/community assessment revealed a drinking water safety of 3%, while nationally it is 0%. There are a great amount of respiratory toxicants in Box Elder County, which consist of carbon monoxide and nitrogen oxide. The county ranked between 70-80% for being the dirtiest counties in the nation when it comes to the cancer risk score, and ranked between 90-100% for a non-cancer risk score based on air releases. There wasn’t any specific data available regarding stray animal health hazards or poisonous plants/allergens, but there is a high amount of sheep wastes.

By using a scatter plot and plotting the number of weeks employed in respect to the ages of the workers, you can see that the points are...

...Prepare a managerial report for the dean of the college that summarizes your assessment of the nature of cheating by business students at Bayview University. Be sure to include the following questions.
1. Develop 95% confidence intervals for the proportion of all students, the proportion of male students, and the proportion of female students who were involved in some type of cheating.
2. Conduct a hypothesis test to determine if the proportion of business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions as reported by the Chronicle of higher education. The article reported 56% of business students.
3. Conduct a hypothesis test to determine if the proportion of business students at bayview University who were involved in some type of cheating is less than that of non business students at other institutions as reported by the Chronicle of higher education. The article reported 47% non business students.
