1) In a multiple regression output, if individual test of slope coefficient for each variable shows that all the independent variables are not significant individually, but test on overall validity of model supports the alternative hypothesis at a specified level of significance, this is most likely due to: A. autocorrelation B. multicollinearity C. the presence of dummy variables D. the absence of dummy variables 2.

8) Suppose the correlation coefficient between two variables is -0.897. Does the dependent variable increase or decrease as the independent variable increases? O a. The dependent variable will decrease as the independent variable increases. O b. The dependent variable will remain constant as the independent variable increases. The dependent variable will remain constant as the independent variable increases. The dependent variable will increase as the independent variable increases.

Given below are four observations collected in a regression study on two variables x (independent variable) and y (dependent variable). *NOOO a. Develop the least squares estimated regression equation. b. At 95% confidence, perform at test and determine whether or not the slope is significantly different from zero. C. Perform an F test to determine whether or not the model is significant. Let a = 0.05. d. Compute the coefficient of determination.

Which of the following is false? Correlation coefficient and the slope always have the same sign (positive or negative). If the correlation coefficient is 1, then the slope must be 1 as well. Correlation measures the strength of linear association between two numerical variables. If the correlation between two variables is close to 0.01, then there is a very weak linear relation between them.

Drop down options are durability, impact properties, shock
absorbing capabilities, the two independent variables.
A regression analysis is performed to predict the durability of a brand of running shoe, based on the shock-absorbing capability and the change in impact properties over time. The resulting ANOVA table is below. Complete parts (a) through (d).

Which of the following, holding all other variables constant, will cause an INCREASE in a constant growth stock's current value? An increase in the number years the stock is held An increase in the market return (k) An increase in the growth rate Both "An increase in the growth rate" & "An increase in the market return (k)" All of these choices are correct.

Factorial designs a) Are generally not appropriate for experimental research b) Measures a single independent variable in depth c) Require an increase in sample size if a pretest is used d) Allow for generalization across variables with an interaction effect is present
8) Suppose the correlation coefficient between two variables is -0.897. Does the dependent variable increase or decrease as the independent variable increases? O a. The dependent variable will decrease as the independent variable increases. O b. The dependent variable will remain constant as the independent variable increases. The dependent variable will remain constant as the independent variable increases. The dependent variable will increase as the independent variable increases.
