H0: Median ≤ $1,200
H1: Median > $1,200
S = 9
n = 9 + 2 = 11
p = 0.50
p-value = P(x ≥ S)
p-value = P(x ≥ 9) = 0.0269 + 0.0054 + 0.0005 = 0.0328
Because our p-value (0.0328) is less than α = 0.05, we reject the null hypothesis. We have enough evidence to conclude that the median roundtrip airfare between New York and London is greater than $1,200.
