Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviation for the given sample data. What do the results tell us? 

58 59 66 57 3 6 42 25 219 56

 Range = 64 (Round to one decimal place as needed.)

 Sample standard deviation = (Round to one decimal place as needed.)

 Sample variance = (Round to one decimal place as needed.) 

 What do the results tell us?

 A. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.


Solutions

Expert Solution

Range is,

Sample standard deviation is,

Where,

Therefore the sample standard Deviation is,

Sample standard deviation = 25.2

The sample Variance is,

= 634.4
