Question

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? 

93 60 33 72 9 5 75 56 37 20 95 

Range = (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. The sample standard deviation is too large in comparison to the range. 

 B. Jersey numbers on a football team do not vary as much as expected. 

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