12. A student hypothesized that as the initial concen- tration of chlorine increased, the bacteria concen-
tration at a given time would decrease. Do the
results of the study support this hypothesis?
F. Yes; At a given time, as the initial concen-
tration of chlorine increased the bacteria con-
centration increased.
G. No; At a given time, as the initial concentra-
tion of chlorine increused the bacteria concen-
tration increased.
H. Yes; At a given time, as the initial concentra-
tion of chlorine decreased the bacteria con-
centration increased.
J. No; At a given time, as the initial concentra-
tion of chlorine decreased the bacteria con-
centration increased.
