Statistics

The data below gives the amount of DDT (in parts per million, ppm) found in the brain tissue of brown pelicans.

Juveniles 0.055 0.050 0.030 0.017 0.015 0.049 0.037 0.037 0.052 Nestlings 0.038 0.032 0.063 0.040 0.020 0.013 0.010 0.047

Assume that both samples are from distributions of the same shape. Is there sufficient evidence to indicate that the median amount of DDT is higher for juvenile pelicans? (a = 0.05)
