Because of wind patterns, Air Canada flights between Vancouver and San Francisco can take different times in each direction. Sample times for flights between these cities, from March 8 to March 18, 1997, are shown. Test the claim that both sets of times come from populations with the same variance. Use a 0.05 level of significance.
