Refer to problem 8-57. Do you believe that the variance of performance times for the K boat is about the same as the variance of performance times for the L boat? Explain. What are the implications of your result on the analysis of problem 8-57? If needed, redo the analysis in problem 8-57.

In problem 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: 12.0, 13.1, 11.8, 12.6, 14.0, 11.8, 12.7, 13.5, 12.4, 12.2, 11.6, 12.9

L boat: 11.8, 12.1, 12.0, 11.6, 11.8, 12.0, 11.9, 12.6, 11.4, 12.0, 12.2, 11.7
