grade 12 bio help! characteristics of population!!?

The northern red-backed vole ( Clethrionomys rutilus) is a mouse-like animal that lives in the Artic. A random sampling survey using ten 1 m2 quadrates collected the following data on the number of vole per quadrate:

2, 0, 4, 1, 5, 3, 0, 4, 2, 1

Assume that the entire sampling area contains suitable habitat for the voles.

a) Using the data provided, estimate the population size of voles if the habitat has an ecological area of 230 m2 show your work

b) What dispersion pattern best describes the distribution of voles samples in this study

    > a) Using the data provided, estimate the population size of voles if the habitat has an ecological area of 230 m2 show your work

    Let's see, you did a census of 10 m^2, and the total area of the place is 230 m^2. So, you would expect there to be 230/10 times as much as what you found when you did your census.

    23 * (2 + 0 + 4 + 1 + 5 + 3 + 0 + 4 + 2 + 1) = 23 * 22 = 506 voles (answer)

    > b) What dispersion pattern best describes the distribution of voles samples in this study

    Probably clumped.
