The statistics were described using mean and standard deviation. I think these would be appropriate if there wasn’t missing information. The percentages don’t total 100% because there is data missing. 3. What other statistic could have been used to describe the length of labor? Provide a rationale for your answer

Central Tendency and Measures of Variation Task 1: 1.1 a.) Define Population: Population is a complete group or collection of items or people selected to be used for a statistical study b.) Define Sample: Sample is a partial selection or part of the population for which the study uses for information gathering. 1.7 The Neilson study is an inferential study; the results contained on the study are not focused and generalized. The population is not defined and therefore inferences are needed

Report Introduction Markowitz (1952‚ 1956) pioneered the development of a quantitative method that takes the diversification benefits of portfolio allocation into account. Modern portfolio theory is the result of his work on portfolio optimization. Ideally‚ in a mean-variance optimization model‚ the complete investment opportunity set‚ i.e. all assets‚ should be considered simultaneously. However‚ in practice‚ most investors distinguish between different asset classes within their portfolio-allocation

standard deviation of the sampling distribution. 4. Assuming no measurement error‚ the reliability of an estimate of a population parameter can be assessed in terms of its standard error. 5. The standard error of the mean can be estimated by using the sample standard deviation‚ s‚ as an estimator of . 6. z values calculate the area under the sampling distribution. 7. When the sample size is over 10% of the population size‚ the standard error formulas overestimate the standard deviation of the

MODEL CREATION Introduction The main purpose of using financial model is to analyse and understand the financial situation of business for decision-making. .Finance needs various calculations to get precise information. There are different types of user e.g. managers and owners need the financial model to evaluate the risk and return to make business decisions for the smooth operation‚ Individual investors make logical investment decisions – ‘’Risk aversion’’ and etc.(Wild‚ Subramanyam and Halsey

Introduction Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time‚ other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms
