Question 1 The coefficient of determination O cannot be negative O can be negative or positive O is the same as the coefficient of correlation O is the square root of the coefficient of correlation Question 2 The standard error is the O square root of SSE O t-statistic squared O square root of SST O square root of MSEQuestion 3 In regression analysis, which of the following is not a required assumption about the error term 6? O The values of the error term are independent. 0 The expected value of the error term is one. Q The variance of the error term is the same for all values of X. 0 The error term is normally distributed. Question 4 In regression analysis, the variable that is being predicted is the 0 dependent variable 0 is usually :4: 0 independent variable 0 intervening variable Question 5 In regression analysis, the independent variable is O the variable that is being predicted 0 called the intervening variable 0 used to predict other independent variables 0 used to predict the dependent variable Question 6 Larger values of r2 imply that the observations are more closelyr grouped about the 0 average value of the dependent variable 0 least squares line 0 origin 0 average value of the independent variables Question 7 In a regression and correlation analysis if r = 1, then O SSR = SST O SSE = 1 O SSR = SSE O SSE = SST Question 8 If the coefficient of correlation is a positive value, then the regression equation O must have a positive y intercept O must have a negative slope O could have either a positive or a negative slope O must have a positive slopeQuestion 9 If all the points of a scatter diagram lie on the least squares regression line, then the coefficient of determination for these variables based on these data is O 1 O either 1 or -1, depending upon whether the relationship is positive or negative O could be any value between -1 and 1 Question 10 The coefficient of correlation O is the square root of the coefficient of determination O can never be negative O is the same as r-square O is the square of the coefficient of determination
