Question
Chapter 2A, Problem 2P
To determine
Dependent and independent variables
Concept Introduction
Independent and Dependent Variable:
There are two main variables for constructing a graph namely, independent variable and dependent variable. The independent variable is a variable that increases or decreases on its own and a dependent variable is a variable that changes depending upon the changes in an independent variable.
Slope of line
The slope of a line represents the change in the value of y due to change in value on the x. The slope of a line is a measure of the steepness of the line.

Using data from 1988 for houses sold in Andover, Massachusetts, from Kiel and McClain
(1995), the following equation relates housing price (price) to the distance from a recently
built garbage incinerator (dist):
=
log(price) 9.40 + 0.312 log(dist)
n = 135, R2 = 0.162.
Interpretation of the slope coefficient?
► How would our interpretation of the slope coefficient change if
distance were measured in metres instead of kilometres?

- CEO Salary and Firm SalesWe can estimate a constant elasticity model relating CEO salary to firm sales. The data set is the same one used in Example 2.3, except we now relate salary to sales. Let sales be annual firm sales, measured in millions of dollars. A constant elasticity model is[2.45]ßßlog (salary) = ß0 + ß0log (sales) + u,where ß1 is the elasticity of salary with respect to sales. This model falls under the simple regression model by defining the dependent variable to be y = log(salary) and the independent variable to be x = log1sales2. Estimating this equation by OLS gives[2.46]log (salary)^=4.822 + 0.257 (sales) n = 209, R2 = 0.211.The coefficient of log(sales) is the estimated elasticity of salary with respect to sales. It implies that a 1% increase in firm sales increases CEO salary by about 0.257%—the usual interpretation of an elasticity.arrow_forwardSolvearrow_forwardAsap please and give with explanation with each steparrow_forward
