Logging activity in forests is thought to affect the behavior of black bears. An important measure of animal behavior is the home range, the area used by animals in their daily lives. In a study of black bears in a logged Canadian forest, the spring and early summer home ranges (in square kilometers) of 12 radio-collared female black bears was measured. The results are below. Assume the home range of female black bears in this logged forest is normally distributed. 39.9, 23.5, 42.1, 29.4, 34.4, 40.9, 27.9, 22.3, 13.0, 20.1, 13.3, 8.6 d) Construct and interpret a 95% confidence interval for the mean home range of female black bears in this logged forest. e) The typical home range of females in forests with no logging is 20 square kilometers. Based on the confidence interval above, do you think that the mean home range size of females in this logged forest could be the same as the mean home range size in non-logged forests? Explain.
