An automobile manufacturer has given its van a 51.5 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the actual MPG for this van since it is believed that the van has an incorrect manufacturer's MPG rating. After testing 190 vans hey found a mean MPG of 39.9 . Assume the standard deviation is known to be 2.4 . Is there sufficient evidence at the 0.05 level that the vans have an incorrect manufacturer's MPG rating?
