The Appalachian Trail is a long hiking trail that takes several months to travel by foot. Hikers sometimes change
sleeping bags during the trip because of changing seasons.
Each sleeping bag has a rating telling the minimum outside temperature in which it is effective. Here are some
summary statistics for the ratings for the sleeping bags hikers were using at the beginning and end of their trip:
Time
Beginning
End
Mean rating Standard deviation
== 21 F
o=11 F
H=32 F
o = 12.9 F
