Suppose x is a random variable best described by a uniform probability distribution with c= 10 and d= 25. a. Find f(x). b. Find the mean and standard deviation of x. c. Graph f(x) and locate u and the interval u + 20 on the graph. Note that the probability that x assumes a value within the interval u± 20 is equal to 1. ..... a. Find f(x). Choose the correct answer below. YA. f(x) = (10sxs 25) 15 O B. f(x) = (10sx) 1 OC. f(x) = (0sxs 25) 10 O D. f(X) = 10 (25 sx) b. Find the mean and standard deviation of x. H= 10.75 o=4.330 (Round to three decimal places as needed.)
