12 A Random Sample Of 46 Adult Coyotes In A Region Of Northern Minnesota Shoed The Average Age To Be X 2 05 Years With 2 (9.93 KiB) Viewed 26 times
12. A random sample of 46 adult coyotes in a region of northern Minnesota shoed the average age to be x=2.05 years, with sample standard deviation of 0.82 (based on information from the book Coyotes: Biology, Behavior, and Management, edited by M. Bekoff, Academic Press). However, it is thought that the overall population mean age of coyotes is u = 1.75 years. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use the P-value method and a significance level of 0.01.
13. Use the scenario of problem 12 but assume x= 1.45 years. Test that coyotes in this region of northern Minnesota tend to live less than the average of 1.75 years.
