I'm interested in seeing if there is a correlation between number of hours someone drives and the amount of fuel ( in gallons) that are left in the tank. I'm starting with a pilot test using data of 4 people. 1st person number of hours driving x=3 , gallons of fuel left y=4, 2nd person x=2,y=5 , 3rd person x=1,y=9 4th person x=6,y=2.
