Measuring drops. Medication is often delivered through an intravenous (IV) drip line that allows a prescribed amount of a drug to be administered at a fixed rate. In this medical context, the standard abbreviation for a drop is gtt(from the Latin gutta, for drop). Each delivery system has a particular frop factor, which is the number of drops per milliliter of solution (with units gtt/mL).
a. A particular macrodrip system has a drop factor of 20gtt/mL. how many drops are in a 0.5L bag of normal saline?
b. A particular macrodrip system has a drop factor of 60gtt/mL. How many drops are in a 1.5L bag of D5W (dextrose)solution?
c. Suppose an entire 1L bag of normal saline is administered in five hours through a system with a drop factor of 15gtt/mL. How many drops were delivered? What was the rate of infusion in gtt/min?

- The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near the shore. Location IV was 200 meters downstream from the discharge point and in midstream. The following table shows the results. Lower dissolved oxygen readings mean more pollution. Because of the difficulty in getting midstream samples, ecology students collecting the data had fewer of these samples. Use a 5% level of significance. Do we reject or not reject the claim that the quantity of dissolved oxygen does not vary from one location to another?
