Q3. A company for fuel stations wanted to check two fuel pumps since there was a doubt that there is a difference in the average pumping time. From previous reconds they knew that Pump 1 has o = 4 mins and Pump 2 has a2 = 3.5 mins. A sample of size 100 from cach pump is tested and they found that the average time for each as i = 10 mins and i = 8.8 mins respectively. Check with the significance of a = 0.05 whet her there is a difference in pumping time or not.
