Question

14. If the correlation between the twoindependent variables of a regression analysis is 0.11 and eachindependent variable is highly correlated to the dependentvariable, what does this indicate?
       Only one of the independent variables should be usedin the regression equation.
       The independent variables are strongly related.
       Two separate regression equations are required.
       Both independent variables should be used to predictthe dependent variable.

15. What does the correlation matrix for amultiple regression analysis contain?
       Multiple correlation coefficients
       Simple correlationcoefficients
       Multiple coefficients of determination
       Multiple standard errors of estimate

16. What can we conclude if the global testof regression does not reject the null hypothesis?
       A strongrelationship exists among the variables
       No relationship exists between the dependent variableand any of the independent variables
       The independent variables are good predictors
       Good forecasts are possible

17. What can we conclude if the global testof regression rejects the null hypothesis?
       Strong correlations exist among the variables
       No relationship exists between the dependent variableand any of the independent variables
       At least one of the netregression coefficients is not equal to zero.
      Good predictions are notpossible

18. For a unit change in the firstindependent variable with other things being held constant, whatchange can be expected in the dependent variable in the multipleregression equation? Y^ = 5.2 + 6.3X1 – 7.1X2
       -7.1
       + 6.3
       + 5.2
       + 4.4

Explanation / Answer

14) Both independent variables should be used to predict thedependent variable. 15) Simple correlationcoefficients 16) No relationship exists between the dependent variable and anyof the independent variables 17) At least one of the net regressioncoefficients is not equal to zero. 18)+ 6.3
