The model in Example 9.3 has only two market outcomes, good and bad, and two corresponding predictions, good and bad. Modify the decision tree by allowing three outcomes and three predictions: good, fair, and bad. You can change the inputs to the model (monetary values and probabilities) in any reasonable way you like. Then you will also have to modify the Bayes rule calculations. You can decide whether it is easier to modify the existing tree or start from scratch with a new tree.
The Baker Company wants to develop a budget to predict how overhead costs vary with activity levels. Management is trying to decide whether direct labor hours (DLH) or units produced is the better measure of activity for the firm. Monthly data for the preceding 24 months appear in the file P13_40.xlsx. Use regression analysis to determine which measure, DLH or Units (or both), should be used for the budget. How would the regression equation be used to obtain the budget for the firms overhead costs?
Stock market analysts are continually looking for reliable predictors of stock prices. Consider the problem of modeling the price per share of electric utility stocks (Y). Two variables thought to influence this stock price are return on average equity (X1) and annual dividend rate (X2). The stock price, returns on equity, and dividend rates on a randomly selected day for 16 electric utility stocks are provided in the file P13_15.xlsx. Estimate a multiple regression equation using the given data. Interpret each of the estimated regression coefficients. Also, interpret the standard error of estimate and the R-square value for these data.

Determine the type of business analytics for the following scenarios. A. Imagine you are a meteorologist. You have to foretell the weather for the next two weeks by analysing the data from the satellites. Here, you have to apply advanced statistical, information software, or operations research methods to identify predictive variables and build predictive models. Discuss in detail which type of business analytics will be suitable for this scenario.

Paraphrase this one. Analyze and elaborate in 120 words. Predictive analytics involves a statistical approach called regression, which helps us uncover connections between different factors. This technique is valuable for spotting trends within extensive sets of information and figuring out how various inputs relate to each other. It shines brightest when dealing with continuous information that follows an established pattern. Regression frequently comes into play when we want to understand the impact of one or more independent factors on another. For instance, it aids in grasping the effect of raising prices on product sales. This tool holds the key to unraveling hidden insights in data that might otherwise remain unnoticed.
