Measures of variability solutions

The variability of a data set as measured by the number R=xmax−xmin. The variability of sample data as measured by the number √Σ(x−ˉx)2n−1. The variability of population data as measured by the number σ2=Σ(x−μ)2N.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
