When making inferences about population variance, what distribution should we use? Select one: O a. Normal distribution O b. t-distribution O c. Chi-squared distribution O d. F-distributionIn a regression model, will a test for Overall Significance yield the same result as a test for Individual Significance? Select one: Q a. It depends on the data set 0 b. It depends on the nature of the dependent variable 0 c. Yes, but only if there is one independent variable 0 cl. No. the outcomes will be different for the two tests When testing for Individual Significance in a regression model, what is the purpose? Select one: 0 a. Find R-Squared for the estimated regression equation 0 b. Detect leverage in the model 0 c. Assess if there is a significant relationship between the dependent variable and a particular independent variable 0 d. Calculate the Goodness of Fit for the regression model What is the implication of a regression coefficient which is significantly different from zero? Select one: 0 a. The corresponding variable is unrelated to the dependent variable at the population level 0 b. The coefficient is zero at the population level 0 c. The corresponding variable is related to the dependent variable at the population level 0 d. The variable is insignificant In a Multiple Linear Regression model, if you are interested in looking into the relationship between the dependent variable and a specific independent variable, what test statistic would you use? Select one: 0 a. F O b. Durbin-Watson O c. t 0 d. Cook's D
