H

: Median ≤ $1,200
H

: Median > $1,200
S

n

p

p

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.
