Question
In a study of speed​ dating, female subjects were asked to rate the attractiveness of their male​ dates, and a sample of the results is listed below
​(1=not
​attractive;
10=extremely
​attractive). Find the​ range, variance, and standard deviation for the given sample data. Can the results be used to describe the variation among attractiveness ratings for the population of adult​ males?

​(Round to one decimal place as​ needed.)
The standard deviation of the sample data is
nothing.
​(Round to one decimal place as​ needed.)
The variance of the sample data is
nothing.

Can the results be used to describe the variation among attractiveness ratings for the population of adult​ males?
 
 
A.
It is unlikely that a random sample of adult males can be representative of all adult males.​ Therefore, the results cannot be used to describe the population.
 
B.
The results can be used to describe the population because the sample is random.
 
C.
Since it is likely that the male subjects volunteered to participate in speed​ dating, they may not be representative of all adult males.​ Therefore, the results cannot be used to describe the population.
 
D.
The results cannot be used to describe the population because a smaller sample would be needed.
