The Normal Distribution and Probability - Essay Example Given that the median helps to do away with influences associated with too much of one or two scores on the extremes of any given distribution, it thus emerges as the measure of choice in variability. Assignment 2 Sales 500 salespeople of a company are mostly normally distributed forming a bell symmetrical shape. Whereby sales from those who record high sales appear on the right side while those with low sales coming on the left side and with a majority of sales appearing on the middle part of the distribution, translating to an average of sales on either side of the curve accounting for the mean sales. This would make it resourceful to come up with a working model to be used to work out a budget as well as predicting performance of the company. A company would predict the effect-increase in sales revenue- of increasing the number stores and salespeople. This distribution also helps to not only identify those sales people who need extra training but also it helps to identify those wh o need to be replaced. It is worth to consider the size of the sample in question, with a large sample like that of the 500 sales people proving to be more representative compared to a sample of about 100 people. It is therefore relevant statistically to estimate that adding one more sales person is worth for instance $25,000 increase in revenue. Clearly from the study sales people and their respective sales are the main variables which are measured in ratio scale since there are those sales people who have nil sales. On using a continuous scale, sales are normally distributed with most of sales in middle range and the entire sales data being within the range 40% of the average sale. A probability value of 0.05 implies 5% of the sales people will sell an amount different from expected sales value and while the remaining 95 % are expected to sell at an amount within the expected amount. This concept is therefore used to represent monthly countable sales. Assignment 3 Organizations re sort to using means such as incentives and bonuses so as to increase the productivity of their employees. In order prove that financial incentives have always boosted the productivity of employees, I will evaluate the hypothesis that a $ 1,000 incentive offered to employees is sufficient to make them finish a project before the expected time. In this study size of incentive and level of productivity are the independent and dependent variables respectively. Assuming the population sample n=30 would be chosen randomly from the employees allocated to new projects. Hypothesis testing is an analysis of a given research, with a null hypothesis indicating a zero change as a result of the $ 1000 incentive represented by  µ. On the other hand a change as a result of the $ 1000 incentive indicates the alternative hypothesis. In order to determine critical boundaries and identify chances of Type 1error, it's important to select an alpha level. Selecting a .01 alpha level provides a low risk error and avoids overstretching the critical area since this level enhances a balance between the functions which offers a base to reject or accept the proposed effect of the incentive. A one-tailed test is utilized when hypothesis about a particular directional rather than general. Results obtained from one -tailed test are of significance

International businesse in emerging market - Assignment Example The emerging market accelerated growth of its international business, which were up 4% LFL. In June 2014, the company planned to invest $20 billion in a gas-fired power complex in Vietnam. In its planning, the company recognized the need to create a partnership with a host well-known company in Vietnam in an attempt to sell its products in this emerging market. It, therefore, collaborated with Vietnam’s state-owned petrol Vietnam. It erected two power plants with a capacity to produce between 6000 and 6500 megawatts of power. In this perspective, the company focuses on capturing the gas and oil market in Vietnam through provision of cheaper prices and diversified oil and gas brands (Regester & Larkin, 2014). It proposed to position its operation in 700 locations and several retail operations. In addition, the strategy aims to present its brands closer to consumers and therefore making its brand most accessible products in Vietnam. Vietnam is one of the top five developing nations in Asia. It has a robust middle class, a crucial driver of economic expansion in a developing country. It is valid to argue that middle class mainly supports the policy change significantly to the success of the country and in supporting capitalist democracy. The country has the fastest-growing middle class in the whole Southeast Asia and is expected to double in size from 12 million (2014) to 32 million by 2020. Generally, Exxon Mobil was experiencing various impending challenges in Vietnam such as complex foreign investment laws, corruption in infrastructure projects, lack of comprehensive and transparent legal system and restricted land usage rights (Plunkett, 2014). However, Vietnam is currently undergoing trade liberalization through negotiations toward a free agreement with the European Union (Van Dyke, et al., 2014). The negotiation presents viable market to Exxon Mobil since its
