An automobile manufacturer wishes to test that claim that synthetic motor oil can improve gas mileage (in miles per gallon, or mpg). The table below shows the gas mileages, in mpg, of six cars that used synthetic motor oil. The table also shows the gas mileages in mpg of six cars that were using conventional motor oil (the controls).

Synthetic	26	27	27	26	28	29
Control	26	25	24	26	27	25

Can you conclude that the mean gas mileage for cars using conventional motor oil is less than the mean for the synthetic motor oil? Use the .01 level of significance.
