Two tire-quality experts examine stacks of tires and assign a quality rating to each tire on a 3-point scale. Let X denote the rating given by expert A and Y denote the rating given by B. The accompanying table gives the joint distribution for X and Y. Can it be said that the ratings given by the two experts are independent? Explain. Click the icon to view the joint probability distribution. . First find the marginal density of both X and Y. Let g(x) be the marginal density of X and let h(y) be the marginal density of Y. х 1 2 3 g(x) Х у 2 Joint probability distribution h(y) (Type integers or decimals. Do not round.) Can it be said that the ratings given by the two experts are independent? Explain. f(x,y) 1 2 3 1 0.11 0.11 0.05 y 2 0.06 0.29 0.11 0.02 0.06 0.19 O A. The random variables X and Y are independent because g(2) = h(2) O B. The random variables X and Y are independent because g(x). h(y)=f(x,y) for all (x,y) within their range. O C. The random variables X and Y are not independent because g(2) = h(2). OD. The random variables X and Y are not independent because g(1).h(1) + f(1,1) Print Done
