In nearly all decision-making models, which of the following is an essential step in the decision-making process?
Weegy: Five Steps of Decision Making: 1. State The Problem , 2. Identify Alternatives, 3. Evaluate The Alternatives, 4. Make A Decision, 5. Implement Your Decision User: A research company has been hired by a realty company to do an analysis of heating cost of homes in the region. The realty company wanted to be able to predict the heating cost of a typical single-family home. The realty company was constantly being asked questions regarding heating costs by potential home buyers. It was believed that these variables would impact heating costs (Y'): mean daily outdoor temperature (X1), the number of inches of insulation (X2), and the age in years of the furnace (X3). The multiple regression analysis produced the following regression equation: Y' = 427.2 – 4.58X1 – 14.83X2 + 6.10X3. Which statement is correct based on this analysis? A. The age of the furnace has an indirect relationship with heating costs. B. There is an inverse relationship between outdoor temperature and heating costs. C. There is no real clear relationship between these variables. D. There exists a direct relationship between inches of insulation and heating costs. Weegy: 1.state the problem,2.evaluate the alternatives,3.identify alternatives,4.implement your decision,5.make your decision (More)

The answer is C. an ANOVA test ; In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical test of whether or not the means of several groups are all equal, and therefore generalizes t-test to more than two groups. Doing multiple two-sample t-tests would result in an increased chance of committing a type I error. For this reason, ANOVAs are useful in comparing two, three, or more means.
