Use the regression output in Appendix A at the end of this document to answer the following questions [Note: PUBS = number of publications; TIME = Number of years since completion of PhD; SALARY = Salary of the instructor]: a. Is this a simple regression model or a multiple regression model? Provide a justification for your choice.
b. How much of the total variation in the dependent variable can be explained by the predictor(s) in this model? What proportion of the total variation remains unexplained?
c. Write down the estimated regression equation?
d. Identify the value of intercept and (partial) slope coefficient(s).
e. Is the intercept of the estimated regression line significantly different from 0 in the population? Why or why not?
f. Is(are) the (partial) slope coefficient(s) of the estimated regression line significantly different from 0 in the population? Why or why not?
g. Interpret the values of estimated regression coefficients.
