15.34 (EX) Deer mice: Deer mice (Peromyscus maniculatus) are small rodents native to North America. Their body lengths (excluding tail) are known to vary approximately Normally with mean μ = 86 mm and standard deviation o = 8 mm. Deer mice are found in diverse habitats and exhibit different adaptations to their environment. A random sample of 14 deer mice in a rich forest habitat gives an average body length of x = 91.1 mm. Assume that the standard deviation o of all deer mice in this area is also 8 mm. In Exercise 14.35 (page 357) you gave a confidence interval based on the body lengths of 14 deer mice (Peromyscus maniculatus) from a rich forest habitat. Before you can trust your results you would like more information about the data. What facts would you most like to know? Select all that apply. (Hint: There are 3 correct answers.) Whether body lengths of deer mice are exactly Normally distributed. Whether the sample of deer mice was random. We would like to verify that no calculation errors were made in computing the confidence interval. We would like to know the standard deviation of the sample. Whether the forest used for the study represents other habitats of deer mice.
