Kristen likes to throw tennis balls for her dog Bucket. Let T = the time it takes for Bucket to chase down a ball, return to Kristen and drop the ball at her feet on a randomly selected throw. T is equally likely to take any value in the interval form 8 seconds to 15 seconds. a) Sketch a graph of the probability distribution of T. Be sure to include a vertical scale. b) Find the probability that, on a randomly selected throw, Bucket returns the ball within 13 seconds. c) C.) Find the mean of T
