2. Logging activity in forests is thought to affect the behavior of black bears. An important measure
of animal behavior is the home
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
39.9, 23.5, 42.1, 29.4, 34.4, 40.9, 27.9, 22.3, 13.0, 20.1, 13.3, 8.6
a) Are the normality criteria met for the sampling distribution of sample means?
b) Identify the sample statistics, ?̅, s and n.
c) Calculate the margin of error E for a 95% confidence interval.
