Question 30 2 pts A computer repair shop has two work centers. The first center examines the computer to see what is wrong and the second center repairs the computer. Let x, and * be random variables representing the lengths of time in minutes to examine a computer (x, ) and to repair a computer (x, ). Assume x, and x, are independent random variables. Long-term history has shown the following mean and standard deviation for the two work centers: Examine computer, x, : #1 = 26.7 minutes; 31 = 8.2 minutes Repair computer, x, : u, = 89.4 minutes; O, = 14.7 minutes Let W = x, + x, be a random variable representing the total time to examine and repair the computer. Compute the mean and standard deviation of W . Round your answer to the nearest tenth. O up = 16.8, Jy = 116.1 O up = 116.1, y = 16.8 O up = 58.1, JW = 282.2 O up = 116.1, Jy = 282.2 O up = 58.1, Jy = 16.8
