CHAPTER 16 SIMPLE LINEAR REGRESSION AND CORRELATION SECTIONS 1 - 2 MULTIPLE CHOICE QUESTIONS In the following multiple-choice questions‚ please circle the correct answer. 1. The regression line [pic] = 3 + 2x has been fitted to the data points (4‚ 8)‚ (2‚ 5)‚ and (1‚ 2). The sum of the squared residuals will be: a. 7 b. 15 c. 8 d. 22 ANSWER: d 2. If an estimated regression line has a y-intercept of 10 and a slope of 4‚ then when x = 2 the actual value

union membership. We will use the technique of linear regression and correlation. Regression analysis in this case should predict the value of the dependent variable (annual wages)‚ using independent variables (gender‚ occupation‚ industry‚ years of education‚ race‚ and years of work experience‚ marital status‚ and union membership). Regression Analysis Based on our initial findings from MegaStat‚ we built the following model for regression (coefficient factors are rounded to the nearest hundredth):

ADO-EKITI‚ NIGERIA E-mail: bishopobey@yahoo.com ABSTRACT This paper investigates the effects of banking sector reforms on economic growth of Nigeria over the period 1986-2010. The study adopts multiple regression analysis of ordinary least square (OLS) and descriptive analysis in establishing the relationship between gross domestic products that proxy economic growth and interest rate‚ exchange rate‚ cash reserve ratio‚ total asset and loan and advances

3.2.3 The Stepwise Regression Analyses Table 4 and 5 showed the result of multiple regression analysis of critical thinking (CT) and speaking Skill (SS) achievement. The correlation among the Debate and context‚ issue‚ implication‚ and assumption was 0.923 or 92.3% and the influence of contribution of the whole aspects of critical thinking (CT) was 0.821 or 82.1%. Partially‚ the contribution of each aspect of critical thinking (CT) toward critical thinking (CT) achievement was as follows: context

Multiple Regression Analysis For hypotheses testing of this study‚ multiple regression analysis was conducted. Some assumptions of the relationship between dependent and independent variables need to be met for performing multiple regression analysis like‚ normality‚ linearity‚ homoscedasticity and multicollinearity (Hair et al.‚ 1998). As mentioned earlier‚ the required assumptions have already been met and multiple regression analysis was appropriate. Usually‚ multiple regression analyses

Regression As the human race ‘evolves’ and progresses it has created an environment unsuitable for the generations to come. This Darwinist environment promotes the ideals of a ‘dog-eat-dog’ world‚ in which one person’s ambitions are more important than another human being’s. People strive for the ideal life in which money is not an issue‚ so the matter of living comfortably is not a problem. To live comfortably is an idea of life without worry of matters such as starving‚ fiscal responsibility

DATA SET 1 Soft Drink Demand Estimation Demand can be estimated with experimental data‚ time series data or cross section data. Sara Lee Corporation generates experimental data in test stores where the effect of an NFL-licensed Carolina Panthers logo on Champion sweatshirt sales can be carefully monitored. Demand forecasts usually rely on time series data. In contrast‚ cross-section data appear in Table 1. Soft drink consumption in cans per year is related to six pack price‚ income per capita

A complete sample is a set of objects from a parent population that includes ALL such objects that satisfy a set of well-defined selection criteria. For example‚ a complete sample of Australian men taller than 2m would consist of a list of every Australian male taller than 2m. But it wouldn’t include German males‚ or tall Australian females‚ or people shorter than 2m. So to compile such a complete sample requires a complete list of the parent population‚ including data on height‚ gender‚ and nationality
