a technician draws 10 cc of a patients blood to be tested for cholesterol and for red blood cells.
c. the variable being studied
i attempted but im not sure if its right...i said
a) the 10 cc of blood
b) the patients blood
c)the blood is being tested but do i out that or what its being tested for
a) and b) look ok. The problem states what the variables are: You want to find the values of cholesterol and red blood cell count. (two variables) Probably the actual variables are
cholesterol concentration (mg/cc)
blood cells (no./cc)
or some such units
