The average range (i.e., R) = Round the final answer to two decimal places, e.g., 0.12, when necessary. The Pet-Pal Company produces delicious dog treats. Management wants the filling process to be properly adjusted so that the process average weight per packet is 45 grams. To make sure that the process is in control, an inspector at the end of the filling process periodically selects a random sample of 8 packets and weighs each packet. The mean and range for each sample are then recorded. The results from the last 5 samples are shown in the table below. Sample Mean Range 1 42 4 2 47 7 3 49 8 4 44 6 5 43 5
