Based on the graph depicting the relationship between two variables, you would conclude the 10 .. Co 6 .. .. . variable 2 4 . . . 2 O a b C variable 1 A. independent variable: discreteominal; relationship best tested with univariate test (e.g. analysis of variance) O B. independent variable: continuous; relationship best tested with bivariate test (e.g. linear regression) O C. dependent variable: discreteominal; relationship best tested with contingency test (e.g. chi-square) O D. dependent variable: continuous; relationship best tested with bivariate test (e.g. linear regression)IA. The study of economics is comprised of three general areas: microeconomics, macroeconomics, and econometrics. What is econometrics? Provide a comprehensive definition of econometrics. IB. What are the two general uses of econometric models? List and briefly discuss both of these. IC. The multiple linear regression model was argued, in general, to be superior to the uni-variate linear regression model for two reasons. Considering your response to IB, discuss the two reasons the multiple regression model is superior.4. A computer program has produced the following ANOVA table for a randomized complete block design, in which each factor appeared once in each block. (30 points) Source Factor Block Error TotalSon:- The given ANOVA table can be completed as; Source d. f. S. S. MSS Treatment 3 498 MST = 166 Block 56 MSB = 28 Error 6 108 MSE = 18 Total 1 1 662 where MST = S.
