Management would like to use simple regression analysis to estimate
monthly car sales using the sales as a function of experience (in
years). Which of the following is true?

Experience is the independent variable. |

Sales is the independent variable |

Not enough information to determine which variable is independent or dependent |

Experience is the dependent variable |

Answer #1

It is given that the management would like to use simple regression analysis to estimate monthly car sales using the sales as a function of experience (in years), i.e. this means that the dependent variable is sales and independent variable is the experience because sales is calculated as a function of experience.

**So, only option A is correct because experience is
the independent variable**

option B is incorrect because sales is not independent variable.

option C is incorrect because we have enough information to determine which variable is independent.

option D is incorrect because experience is not dependent variable

Ford would like to develop a regression model that would predict
the number of cars sold per month by a dealership employee based on
the employee's number of years of sales experience (X1), the
employee's weekly base salary before commissions (X2), and the
education level of the employee. There are three levels of
education in the sales force—high school degree, associate's
degree, and bachelor's degree. The following dummy variables have
been defined.
Degree
X3
X4
High School

Associate's...

Based on a sample of 30 observations the population regression
model to predict salary of employees (dependent variable, numerical
continuous) based on independent variables:
education, measured as number of years of education
(numerical, discrete but so many values),
work experience, measured as number of years of work
experience (numerical, continuous, for example 3.5 means 3 years 6
month work experience)
department, department of the employee, There are three main
departments in the organization (categorical nominal) Assume it
affects only intercept...
