Test statistics that follow a chi-squared distribution arise from an assumption of independent normally distributed data, which is valid in many cases due to the central limit theorem. A chi-squared test can be used to attempt rejection of the null hypothesis that the data are independent.
Voles, also known as mice, live in field, forest, and shrub habitats. Voles can cause extensive damage when they move into our turf and landscaped gardens in search of food and shelter. Voles do not hibernate and are active throughout the year. They can reproduce year round having many litters per year.
Painted turtles are the most widely distributed turtle in North America. They live in permanent freshwater habitats such as ponds, lakes, marshes, sloughs, and creeks. They spend time in the soft bottoms of these bodies of water as well as in the aquatic vegetation and in sunny basking spots on or near the water.
