Statistics Assignment - Speech or Presentation Example The probability of winning the lottery is then around nine in a billion. It should be noted that the resulting equation actually simplifies to a multiplication rule. However, the binomial distribution may be used to model more complex lottery options. In the construction of a 5-digit number, the order in which is numbers are drawn is clearly important. Also, since repetition of digits is not allowed, a single digit chosen is removed from the pool of possible succeeding digits. These conditions indicate that the total number of digits can simply be taken using a permutation. The given table can only be classified as a probability distribution if its individual probabilities are between zero and one and the total probability is equal to one. In the given table, the probability at X = 2 is greater than one. Since no negative probabilities are present, the total probability is also greater than one. As both requirements are not met, the table cannot be a probability distribution. The sample data is relatively sparse (n To determine whether a relationship exists between the two variables, the given data may be fitted onto a function. The simplest approach is to use a linear model for approximating the relation. To aid in this, a column representation may be constructed. It should be noted that the independent variable based on the description is the cost of the product. An assumed frequency distribution is assumed in this case which allows the use of the Goodness of Fit test. The computations for the chi square statistic can then be determined as shown in the following table: Data is a very important

It considers the external factors those which can be viewed as the basis for human behavior. Resource allocation theory is a direct measure of the keenness and effort of an individual to accomplish the task effectively. It is based on certain expectations from the attainment of the tasks based on the success from the past experiences. It is the desire of the individual to contribute effort for the task accomplishment. For instance, as explained by John Whitmore (2009), self motivation can be considered as an inevitable ‘winning ingredient’ if individuals have the desire to attain self-worth and identity (p. 107). As the name suggests, goal orientation perspective refers to individuals’ response to proposed goals. It implies individuals’ attempt to accomplish their wishes set as personal goals.

Theoretical Concepts Underpinning Portfolio Diversification Assignment

Theoretical Concepts Underpinning Portfolio Diversification - Assignment Example The benefits from the process of diversification can only be accrued if the securities within the portfolio are perfectly uncorrelated. The first form of diversification takes place when the company has the potential to develop beyond the existing product market. The related form of diversification can be further categorized into backward diversification, forward diversification, and horizontal diversification. Unrelated diversification takes place when an organization has the potential to develop interests that are complementary to its existing activities. When a company involved in media services can think of diversification in financial services, such kind of diversification is called unrelated diversification (Chatterjee and Wernerfelt, 1991). ... The diversification speed of the value at risk is regarded as the rate at which the value at risk changes because the number of assets included in the portfolio increases. (Ansoff n.d. p. 113). 3The criteria of value at risk are evaluated at a probability level that is fixed. One can also launch the converse analysis where the level of the value at risk is kept fixed and the level of the probability changes with an increase in the number of assets. A majority of the theoretical literature in finance assumes that returns are distributed normally. The speed of diversification is different in cases of normal and other distributions. The diversification speed is higher for the finite variance classes relative to the speed of normal distribution. The speed is lower relative to the speed of the diversification of the risk level (Hyung and Vries, 2004, p. 3). 4 Suppose there are two stocks one with return 0f 8% and another with 15%. The expected range of return of the investor is 8% to 15%. The standard deviation of the former stock is .05 while that of the later is 2. The investor will quantify the associated risk of the two assets and diversifies the investments accordingly. Country wise diversification can also arrive in the scenario (Marineilli, 2011, p. 2). 5 Measurement of the benefits of Diversification Suppose A and B are two portfolios. The former portfolio has an expected return and returns volatility of 7.5% with the qual weighing of both types of assets. But the later portfolio is leveraged in such a way that the weighing of the risk-free asset is -50% while that of the risky asset is 150%.

Emerson calls for the emergence of an American poetics Essay

Emerson calls for the emergence of an American poetics - Essay Example In what ways does William Cullen Bryant move away from imitating British poetry and address American themes? In what ways does he play by the familiar rules of the epic tradition? In ‘The Prairies’, Bryant can be felt to exude the poet-function which Emerson necessitates by rendering his literary work converge to a ‘transcendentalist’ perspective. Though it is conspicuous in depicting the ‘nature of nature’ or the way nature is in its downright truth, ‘The Prairies’ brings about discernment of a kind of spirituality attached with nature which essentially surpasses the mere drawing of relevant sentiments toward its physical attributes. Similarly, Bryant emerges to possess a level of authenticity according to the standards set by Emerson for the American poetics based on his poem’s strong sense of individuality which is a typical element in American themes upon almost every form of American literature. As such, Bryant projects an open mind capable of sensibly resonating back to the reader the deeper essence of ‘The Prairies’ which establishes its identity after the poet’s unique insight.

Lab identification of Clostridum difficil - Essay Example Antibiotics are common in altering the colonic flora, thus the correlation. Today, the infection has attained a global threat level, with deaths in large economies such as the United States estimated at above 14,000 per year. Diagnosis of Clostridium difficile is usually complicated since its outcomes are similar to those shown by other bacteria such as Campylobacter spp., Clostridium perfringens, or Salmonella spp. Several diagnostic methods exist, such as Colonoscopy, stool assays, and medical imaging, vary in their level of efficacy. This study will expound on the several diagnostic techniques of Clostridium difficile with regards to their effectiveness towards its assessment and treatment. Several indicators may lead indicate that one has the Clostridium difficile infection. Common symptoms include excessive recurrent dehydration, fever, tenderness in the lower abdomen, fever in some cases, general body discomfort (malaise), cramping abdominal pain, and diarrhoea that might be watery or in rare cases, bloody. Further suspicion might arise if these symptoms occur in patients who have received antibiotic treatment within three months’ time. Additionally, patients who are hospitalized also stand higher chances of contracting the Clostridium difficile infection. Finally, the diagnosis for the infection might be necessary if a hospitalized patient has recurring diarrhoea for about forty-eight hours. Although most of the mentioned cases are mostly within hospital settings, Clostridium difficile is also common away from medical centres. The risk of infection by Clostridium difficile depends on two factors; the exposure to the bacteria and exposure to antibiotics. The occurrence of Clostridium difficile is highest in infants, accounting for about 84.4%. Residents in long-term care facilities come second with about 57% occurrence, while occurrence in healthy adults accounts for about 5-15%.
