Use α = 0.05 to test the hypothesis that there is no difference between the median percent of on-time arrivals for the two years.
State the null and alternative hypotheses.
Ho: Median percent on-time in 2006 - Median percent on-time in 2007 = 0
H₂: Median percent on-time in 2006 - Median percent on-time in 2007 + 0
OH: Median percent on-time in 2006 - Median percent on-time in 2007 20
H₂: Median percent on-time in 2006 - Median percent on-time in 2007 < 0
