This is the exercise problems solution of the 9th edition of "Probability and Statistics for Engineers and Scientists by Walpole". In this video, I solve exercise problem 4.58 to find the expected value of the scaled and transformed random variable by using the probability density function for discrete probability functions. 4.58 The total time, measured in units of 100 hours, that a teenager runs her hair dryer over a period of one year is a continuous random variable X that has the density function f(x) = ⎧x, 0 x 1, ⎨2 − x, 1 x 2, ⎩0, elsewhere. Use Theorem 4.6 to evaluate the mean of the random variable Y = 60X2 + 39X, where Y is equal to the number of kilowatt hours expended annually. Thank you for visiting the channel.
