An automobile manufacturer claims that their jeep has a 36.5 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this jeep. After testing 13 jeeps they found a mean MPG of 36.8 with a standard deviation of 2.3. Is there sufficient evidence at the 0.05 level that the jeeps outperform the manufacturer's MPG rating?
