A factory process requires 3 steps to finish a product. The steps each have a mean completion time of pl = 10 seconds and a standard deviation of o = 5 seconds. The time it takes to complete each step is independent
from the other steps. Let T be the total completion time of the 3 steps on a randomly chosen product
Find the mean of T.
UT =
seconds
