Two boats, the Prada (Italy) and the Oracle (U.S.A.), are competing for a spot in the upcoming America’s Cup race. They race over a part of the course several times. Below are a sample of times in minutes for each boat. Assume the population standard deviations are not the same. At the .05 significance level, can we conclude that there is a difference in their meantimes?
