ABSTRACT
In this chapter, the authors cover how to estimate the characteristics of a population from samples. The normal distribution of population is represented by a graphical method where the x-axis denotes the ant size in millimeters, which ranges from 4 to 11. The y-axis denotes the frequency from 0.0 to 3.0, with an increasing order of 0.5 units. The frequency increases with the size of the ant. The normal distribution of population is represented by a graphical method where the x-axis denotes the ant size in millimeters, which ranges from 2 to 14 with an increasing order of 2 units, and the y-axis denotes the frequency, which ranges from 0 to 25 with an increasing order of 5 units. The degrees of freedom with a normal distribution are represented in the graphical method, where the x-axis denotes the mean ant size estimate in millimeters, which ranges from 0 to 10000 with an increasing order of 2000 units.
