Essay Title: Describe and explain the population distribution of Brazil. Population distribution means the pattern of where people live. The world’s population distribution is very uneven. Places which are sparsely populated contain few people and places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. These are usually places with hostile environments e.g. Antarctica. Places which are densely populated are habitable environments e.g

13. Variance and Standard Deviation (expected). Using the data from problem 13‚ calculate the variance and standard deviation of the three investments‚ stock‚ corporate bond‚ and government bond. If the estimates for both the probabilities of the economy and the returns in each state of the economy are correct‚ which investment would you choose considering both risk and return? Why? ANSWER Variance of Stock = 0.10 x (0.25 – 0.033)2 + 0.15 x (0.12 – 0.033)2 + 0.50 x (0.04 – 0.033)2 + 0

Standard Deviation in the Business World QRB/501 Abstract On Standard Deviations in Job Performance The purpose of this study was to compare the expected payoffs from personnel programs based on standard deviation of job performances in dollars‚ the Global Estimation model‚ and the CREPID procedure. The study was done for route salesmen of a large soft drink bottling company. The Global Estimation model and the CREPID procedure were behaviorally based‚ where the standard deviation of job performance

Population distribution is how people are dispersed over a given area. Population distribution is measured by persons per square kilometer. An area (or country) can be densely populated‚ which means there is a high concentration of persons per square kilometer‚ or sparsely populated‚ which means there is a low concentration of persons per square kilometer. The distribution of population can be influenced by both physical and human factors. Physical factors include relief‚ climate‚ vegetation‚ soil
