Now consider a production process with three

Now consider a production process with three sequential processes, P1, P2 and P3; the processing times at each of the process is normall distributed as follows (all times in minutes): Process 1: mean 37, standard deviation, 14 Process 2: mean 54, standard deviation, 23 Process 3: mean 115, standard deviation, 22 The labor per minute labor cost at each process is as follows: Process 1: C1=$0.86 /min Process 2: C2= $2/min Process 3: C3= $1.85/min Total time of production for a given unit product is T = time taken at P1+ time taken at P2 + time taken at P3 Total cost of production for a given unit product is C = labor cost incurred at P1+ labor cost incurred at P2 + labor cost incurred at P3 You are supposed to determine the mean and standard deviation of T and C. T: mean time = hours; standard deviation of T = hours (round to the nearest Integer) C: mean time = $ standard deviation of C = $ (round to TWO places of decimal)
