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 2 be random variables representing the lengths of time in minutes to examine a computer ( x, ) and to repair a computer (x2 ). Assume x, and x2 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; Of = 8.2 minutes Repair computer, *2 : #2 = 89.4 minutes; J, = 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 uy = 16.8, J. = 116.1 O uy = 116.1, 5. = 16.8 O up = 58.1, a = 282.2 O uy = 116.1, J. = 282.2 O uy = 58.1, J. = 16.8
