The accompanying data on blood mercury concentration {ugfgj for adult females near contaminated rivers in a state was read from a graph in an article. mummmmmm ummmama l USE SALT [a] Determine the values ofthe sample mean and sample median.

D It is above both the mean and the median. D It is the same as the mean. D It is the same as the median. D It is between the values ofthe mean and median.
