Transcribed Image Text:Some people believe that different octane gasoline result in different miles per gallon in a vehicle. The following
data is a sample of 11 people which were asked to drive their car only using 10 gallons of gas and record their
mileage for each 87 Octane and 92 Octane.

Do the data support that different octanes produce different miles per gallon at the a = 0.02 level of
significance? Note: A normal probability plot of difference in car mileage between Octane 87 and Octane 92
indicates the population could be normal and a boxplot indicated no outliers.
