Two fuel additives are being tested to determine their effect on gas mileage. Seven cars were tested with additive 1 and nine cars were tested with additive 2 . The following data show the miles per gallon obtained with the two additives. Use α=.05 and the MWW test to see whether there is a significant difference in gasoline mileage for the two additives. [ Additive 1 amp; Additive 2; 17.3 amp; 18.7; 18.4 amp; 17.8; 19.1 amp; 21.3; 16.7 amp; 21.0; 18.2 amp; 22.1; 18.6 amp; 18.7; 17.5 amp; 19.8; amp; 20.7; amp; 20.2 ]
