Logging Activity in Forests Is Thought to Affect the Behavior

question 8

Essay

Logging activity in forests is thought to affect the behavior of black bears (Ursusamericanus). An important measure of animal behavior is the home range, the area used byanimals in their lives. In a study of black bears in a logged Canadian forest, the spring andearly summer home range (in km² ) of 12 radio-collared female black bears was measuredwith the following results:
a) Construct and interpret a 95% confidence interval for the mean home range of femaleblack bears in this logged forest.
b) The typical home range of females in forests with no logging is 20 km² . Based on theconfidence interval from part (a), do you think that the mean home range size of femalesin this logged forest could be the same as the mean home range size in non-loggedforests?
