The development of linear programming has been ranked among the most important scientific advances of the mid 20th century. Its impact since the 1950’s has been extraordinary. Today it is a standard tool used by some companies (around 56%) of even moderate size. Linear programming uses a mathematical model to describe the problem of concern. Linear programming involves the planning of activities to obtain an optimal result‚ i.e.‚ a result that reaches the specified goal best (according to the mathematical

Marketing by Numbers Exercise Set One 1.1 Sanborn‚ a manufacturer of electric roof vents‚ realizes a cost of $55 for every unit it produces. Its total fixed costs equal $2 million. If the company manufactures 500‚000 units compute the following: a) unit cost unit cost = variable cost + fixed cost/unit sales x = $55 + $2‚000‚000/500‚000 = $59 unit cost b) markup price if the company desires a 10% return on sales unit cost/(1 – desired return on sales) $59/(1 - .10) = $65.56 c)

The simple regression model (SRM) is model for association in the population between an explanatory variable X and response Y. The SRM states that these averages align on a line with intercept β0 and slope β1: µy|x = E(Y|X = x) = β0 + β1x Deviation from the Mean The deviation of observed responses around the conditional means µy|x are called errors (ε). The error’s equation: ε = y - µy|x Errors can be positive or negative‚ depending on whether data lie above (positive) or below the conditional

Linear Modeling Project The purpose of this experiment is to determine whether a player’s statistics in baseball are related to the player’s salary. The sample set was taken out of 30 players who were randomly selected from the top 100 fantasy baseball players in 2007. We displayed the information with a scatter plot‚ and then determined with a linear equation the line of best fit. Along with the line of best fit we are going to analyze the Pearson Correlation Coefficient. This value is represented
