STUDENT HANDOUT STATWAY™ STUDENT HANDOUT  8 Lesson 10.2.2 Confidence Intervals for a Population Mean 2 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 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. 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...
