(10 pts) The aging algorithm with a 1/2 is being used to predict run times. The previous four runs, from oldest to most recent, are 8, 12, 9, and 11 msec. What is the sequence of predicted runtimes starting with the first of the observed runs (8), ending with the predicted runtime after the last observed run (11).
