      Age       
 Min.   :15.00  
 1st Qu.:19.00  
 Median :25.00  
 Mean   :25.13  
 3rd Qu.:30.50  
 Max.   :40.00  

Running qqnorm/qqline to test to see how normal the data is I got this...

And then I did a boxplot...

Then a t.test (using alpha level 0.05)

One Sample t-test

data:  RP1$Age
t = 19.896, df = 30, p-value < 2.2e-16
alternative hypothesis: true mean is not equal to 0
95 percent confidence interval:
 22.54966 27.70840
sample estimates:
mean of x 
 25.12903 

Median: 25 years old. the p-value is below the 0.05 alpha level... so it is statistically significant. 

n = 31

Looks like sagging is for the men in their mid-20s. lol
