Two 12-meter boats, the K boat and the L boat, are tested as possible contenders in the America’s Cup races. The following data represent the time, in minutes, to complete a particular track in independent random trials of the two boats: K boat 12 13.1 11.8 12.6 14 11.8 12.7 13.5 12.4 12.2 11.6 12.9 L boat 11.8 12.1 12 11.6 11.8 12 11.9 12.6 11.4 12 12.2 11.7 Can we assume equal variances for the two population of boats? Test whether the two boats perform equally well. Is one boat faster, on average than the other?
