Suppose Coach Theil wants to measure the performance of all the track athletes. He wants to specially track the effect of their diet (Diet, measured in grams or g) a their field performance (Performance, measured in meters per second or m/s). Other coaches also include intensity of the field training (Training) and sufficient rest (Rest) as parameters while evaluating athletes' performances. HP, denotes the intercept of the population regression line and Heher denotes the error term, which of the following equations describes the regression Coach Thei wants to run? A. Performance = fo +PDiet * Diet + Hother B. Performance *Praining X Training + Hother C. Diet Po +PRest * Performance * Hother OD. Diet= fo * Ppertomance X Performance + Hother The variables explicitly excluded from Coach Theil's population regression line are incorporated in Which of the following statements are true in describing the coefficients of the regression line when Po62 m/s? (Check all that apply.) DA. The siope, Powr is the change in performance due to a unit change in the diet. B. The slope, Poet is the percentage change in performance due to a unit change in the diet. C. For a given diet X, the intercept shows the predicted value of performance of the athletes when the diet is zero, So, the value of intercept has a significant real-world relevance as it highlights the athletes' performance without a diet. OD. For a given diet X, the intercept shows the predicted value of performance of the athletes when the diet is zero. As a zero diet is improbable, the value of the intercept would have no real-world meaning in this case. Suppose the slope of the regression line is 0.12 and no other factors affect athletes' performance apart from their diet. If the athletes' performance improved by 3.30 m/s within a month, the change in their diet in this month would have been9
