Diabetes is a disease affecting the insulin producing glands of the pancreas.  If there is not enough insulin being produced by these cells, the amount of glucose in the blood will remain high.  A blood glucose level above 140 for an extended period of time is not considered normal.  If not brought under control, this disease can lead to severe complications and even death.

Answer the following questions concerning the data below and then graph it.
