A random sample of 49 adult coyotes in a region of northern Minnesota showed the average age to be 2.09 years, with a sample standard deviation of 0.85 years. However, it is thought that the overall population mean age of the coyotes is 1.76 years. Match the numerical values from the problem to the corresponding symbols below. If a symbol does not have a corresponding value, mark it as "DNE."
