Extraction and Quantitative Determination of B-Carotene Introduction The study of B-Carotene is important because it is good for vision‚ immunity‚ and overall health. The purpose of this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this

The History Of Beta The year of 1934 was the year that saw many exciting events and changes throughout the world… The Dionne sisters (the first quintuplets to survive birth) were born in Canada‚ The St. Louis Cardinals defeated the Detroit Lions for the World Series‚ Vitamin K was discovered by Henrik Dam‚ and a first class stamp cost $0.03‚ but the most exciting event by far happened when the National Beta Club began as the dream of Dr. John W. Harris‚ a professor at Wofford College in Spartanburg

BETA MANAGEMENT COMPANY Q1. Calculate the variability (standard deviation) of the stock returns of California REIT and Brown Group during the past 2 years. How variable are they compared with Vanguard Index 500 Trust? Which stock appears to be riskiest? The stock returns for each month are given in Table 1. Based on the monthly returns‚ the standard deviation or variability of each stock has been calculated. The standard deviation for California REIT is 9.23% and the standard deviation for Brown

Part 1 ’’ A Measurement of Risk 1.1 Risk 1.2 Capital Asset Pricing Model The estimation of systematic risk (or ‘beta’) is central to the implementation of the capital asset pricing model (CAPM) for researchers and practitioners. Markowitz (1952) argued that investors should be concerned with holding efficient portfolios‚ that is‚ a portfolio offering the highest expected return for each level of risk. Sharpe (1964) and Lintner (1965) took Markowitz’s work one step further to develop the CAPM

III. The Arrow-Pratt coefficient Considering Bernoulli’s proposition that utility matters over wealth for risky behavior‚ and adding the fact that no two economical agents are alike‚ we can state that risk aversion can vary very widely across individuals. In this section we examine the coefficient determined by the two economists Kenneth arrow and John Pratt. In order to develop models for dealing with risk in business‚ economists need precise measurements which can be used in sectors such as

GINI COEFFICIENT The Gini coefficient is a summary statistic that measures how equitably income is distributed in a population. It is derived from the Lorenz curve which plots the cumulative percentages of the income and the population against which it is distributed. The line at 45 degrees thus represents perfect equality of incomes. The Gini coefficient is the ratio of the area that lies between the line of equality and the Lorenz curve divided by the total area under the line of equality. A
