Q:
The slope of the regression line, y = 21 - 5x, is 21.
Q:
The slope of the regression line, y = 21 - 5x, is 5.
Q:
The first step in simple regression analysis usually is to construct a scatter plot.
Q:
In regression, the predictor variable is called the dependent variable.
Q:
In regression, the variable that is being predicted is usually referred to as the independent variable.
Q:
The process of constructing a mathematical model or function that can be used to predict or determine one variable by another variable is called regression analysis.
Q:
The strength of a linear relationship in simple linear regression change if the units of the data are converted, say from feet to inches.
Q:
If the correlation coefficient between two variables is -1, it means that the two variables are not related.
Q:
Correlation is a measure of the degree of linear relationship between two variables.

Q:
BigShots, Inc. is a specialty e-tailer that operates 87 catalog Web sites on the Internet. Kevin Conn, Sales Director, feels that the style (color scheme, graphics, fonts, etc.) of a Web site may affect its sales. He chooses three levels of design style (neon, old world and sophisticated) and randomly assigns six catalog Web sites to each design style. In Kevin's experiment "style" is _______.a) the dependent variableb) a treatment variablec) a concomitant variabled) a blocking variablee) a response variable
Q:
While reviewing staffing plans for a new pilot plant, Colin Chenaux, VP of Operations at Clovis Chemicals, Inc., designed an experiment to test the effects of "supervisor's style" and "training method" on the productivity of operators. The treatment levels were: (1) authoritarian, and participatory for supervisor's style, and (2) technical manuals, training films, and multimedia for training method. Three qualified applicants were randomly selected and assigned to each of the six cells. Analysis of Colin's data produced the following ANOVA table. Source of Variation

Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%). First, she classified DCI's credit customers into three categories by total assets (small, medium, and large). Then, she randomly assigned four customers from each category to a sales discount rate.

Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%) by randomly assigning five customers to each sales discount rate. An analysis of Cindy's data produced the following ANOVA table. Source of Variation
