(15) In commuting to work, a person must firstly get on a bus near her home, and then transfer to a second bus. The total waiting time is denoted by the continuous random variable, Y, and has probability density function. 1225 - Y 25 if 0 < y < 5 *y if 5≤ y ≤ 10 f(y) = = Sketch the graph of ƒ (y). Show that 0. f(y)d(y) = 1. otherwise What is the probability the total waiting time is between 3 to 8 minutes? Compute the expected value and variance of Y.
