The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance, and standard deviation of the population data set. 2, 10, 15, 4, 11, 10, 15, 10, 2, 10

a

b

c

d

Step-by-step explanation:

From the question we are given a data set  

      2, 10, 15, 4, 11, 10, 15, 10, 2, 10

     The sample size is  n  = 10

 The range is  

Where maxNum  is the maximum number on the data set  which is 15

 and  MinNum  is the minimum  number on the data set  which is  2

   So

The mean is mathematically represented as

substituting values

The variance is mathematically evaluated as

substituting values

The standard deviation is  

substituting values
