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.

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