An economic research firm ranked the 40 best-paid ceos. the data were collected on a ceo's age and ratio of salary to a typical worker's pay at the firm. one objective is to predict the ratio of salary to worker pay based on the ceo's age a. in this study, identify the dependent and independent variables. b. explain why a probabilistic model is more appropriate than a deterministic model. c. identify the equation of the straight-line, probabilistic model a. choose the correct answer below. 0 a. the independent variable is the ratio of ceo salary to worker pay and the dependent variable is the ceo's age. o b. the independent variable is the ceo's salary and the dependent variable is the ceo's age. o c. the independent variable is the ceo's age and the dependent variable is the ratio of ceo salary to worker pay. o d. the independent variable is the ceo's age and the dependent variable is the ceo's salary. b. choose the correct answer below. o a. there could be some unexplained variation in the dependent variable due to variables other than the independent variable used here o b. the relationship between the independent and dependent variables is not linear. o c. the relationship between the independent and dependent variables is random. o d. there could be some unexplained variation in the independent variable due to random phenomena. c. choose the correct answer
