Homework Answers
Ans: Two variables are said to be correlated if they move together.
Explanation:
Two variables are said to be correlated if they move together either in same direction or opposite direction.If the two variables moves in opposite direction then it will show a negative relationship between two variables and vice versa.
Ans: The goodness of the fit of a line is measured by the R2 statistic.
Explanation:
R2 statistic is used in regression analysis.

When two explanatory variables are highly correlated, should you remove one of the correlated explanatory variables to reduce the multicollinearity problem. A. Yes, it will reduce the standard errors on the coefficients and increase the t statistics. B. No, it will not affect the t statistics on the coefficients. C. No, it will cause the coefficient on the remaining variable to be biased. D. Yes, it will improve the fit of the regression model.

Two variables X and Y are said to have a spurious correlation if their correlation solely reflects each variable's relationship to a third (antecedent) variable Z (and possibly to other variables).

Consider the regression output below and answer each question.
The frequency is quarterly,and the variables are defined at annual

INF_RATE is the inflation rate, UNRATE is the unemployment rate,
and EMP_GROWTH corresponds to the employment growth rate.
a)How is the goodness of fit? How can you tell?
b)For each of the 3 independent variables in the regression,

The equation of the regression line between two variables x (independent variable) and y (dependent variable) is given by y-hat = -3x + 2; and the correlation coefficient is r = -.95. The possible x-values range from 1 to 10. Which of the following statements are correct? I. The variable y is strongly positive correlated to the variable x. II. The variable y is strongly negative correlated to the variable x. III. If x = 5, one would predict that...
