Teenagers diastolic blood pressure 
VS
 adults blood pressure
 

 

 

 

 



Side by side boxplots.  The range for adults is much greater than the range for teenagers.  This is inconclusive data because there are only 12 teenagers, versus 30 adults.


 

 

 

 


The teenagers histogram is less varied compared to the adults which have peeks at 70 and 60.  Neither of the graphs have a normal distribution.

 

Descriptive Statistics for adults

Descriptive Statistics for teenagers

Two sample T for teenagers vs adults

 

           N      Mean     StDev   SE Mean

teenager  12      73.0      12.6       3.6

adults    30      71.6      15.5       2.8

 

95% CI for mu teenager - mu adults: ( -8.1,  10.9)

T-Test mu teenager = mu adults (vs not =): T = 0.30  P = 0.76  DF = 24

 

 

The probablity that the relationship between adults and teenagers is equal is high, therefore there is not a significant relationship between the two.
