Answer: Determine the number of pumps in each of the two six-pump gas stations.
• X = the total No. of pumps that are in use at the 2 stations
• Y = the difference between the No. of pumps in utilization at station 1 and the
NO. of pumps in use at the station 2
• U = the max number of pumps in use at the 2 stations
W (observed) = (3, 4)
X (W) = 3 + 4 = 7
Y (W) = 3 − 4 = − 1
U (W) = max (3, 4) = 4
