Answer:
1)
Weights: [tex]c_{v}[/tex]=0.06321578
Ages: [tex]c_{v}[/tex]=0.06980003
2) A) Ages are more variable than weights for all wide receivers on this team
Step-by-step explanation:
The coefficient of variation [tex]c_{v}[/tex] is calculated as follows
[tex]c_{v} =\frac{s}{x}[/tex]
where s is the sample standard deviation and x bar is the sample mean,
where
[tex]s^{2} =[/tex]∑(xi-x bar)^2/(n-1)
xi=i observation, n is the sample size
and, x bar = ∑(xi) / n
