The Normal diffusion and Probability - Essay ExampleGiven that the median helps to do away with influences associated with too much of unmatched or two scores on the extremes of any given distribution, it thus emerges as the measure of option in variability. Assignment 2 Sales 500 sales populate of a company ar mostly ordinarily distributed forming a bell symmetrical shape. Whereby sales from those who record high sales appear on the chasten facial expression while those with low sales coming on the left side and with a mass 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 modeling to be used to work out a budget as well as predicting cognitive operation 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 non only call those sales people who need extra training but also it helps to identify those who need to be replaced. It is worth(predicate) to consider the size of the example in question, with a large sample like that of the 500 sales people proving to be more representative compared to a sample of more or less 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 go 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 get by an amount different from anticipate sales value and while the remaining 95 % are expected to sell at an amount within t he expected amount. This concept is therefore used to represent monthly countable sales. Assignment 3 Organizations resort 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 take to before the expected time. In this study size of incentive and level of productivity are the individual and dependent variables respectively. Assuming the population sample n=30 would be chosen randomly from the employees allocated to immature projects. Hypothesis testing is an analysis of a given research, with a null hypothesis indicating a zilch change as a result of the $ 1000 incentive represented by . On the new(prenominal) hand a change as a result of the $ 1000 incentive indicates the alternative hypothesis. In order to determine critical bou ndaries and identify chances of Type 1error, its important to select an important level. Selecting a .01 alpha level provides a low risk error and avoids overstretching the critical area since this level enhances a correspondence between the functions which offers a base to reject or accept the proposed effect of the incentive. A one-tailed test is utilize when hypothesis about a particular directional rather than general. Results obtained from one -tailed test are of consequence
