APPLIED OPERATIONAL RESEARCH FOR MANAGEMENT NOTES 1 ANNA UNIVERSITY CHENNAI UNIT I INTRODUCTION TO LINEAR PROGRAMMING (LP) INTRODUCTION Operations Research (OR) (a term coined by McClosky and Trefthen in 1940) was a technique that evolved during World War II to effectively use the limited military resources and yet achieve the best possible results in military operations. In essence you can state that OR is a technique that helps achieve best (optimum) results under the given set of limited

values were then used to create a scatter plot so that we could see the price differentials in a visual format. Then‚ a linear regression line was added to show the increase throughout the years in a linear fashion‚ thereby helping us determine where the prices will average out to in the years to come. There are‚ of course‚ things that may greatly change the course of the linear regression line that cannot

estimate how sales are influenced by the price of their product. To do so‚ the company randomly chooses 6 small cities and offers the candy bar at different prices. Using the candy bar sales as the dependent variable‚ the company will conduct a simple linear regression on the data below: Prics ($) | Sales | 1.30 | 100 | 1.60 | 90 | 1.80 | 90 | 2.00 | 40 | 2.40 | 38 | 2.90 | 32 | | | What is the estimated slope (b1 for this data set? 161.3855 0.784 -0.3810 -48.193 POINT

The goal was to chart previous data collected by experts to support my hypothesis as well as predict and test the size of human brains in the future if the trend continued and develop a linear equation to represent the findings.
