14.9 The concentration of E. colibacteria in a swimming area is monitored after a storm:
t(hr)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 4Â Â Â Â Â Â Â Â Â Â Â 8Â Â Â Â Â Â Â Â Â 12Â Â Â Â Â Â Â Â 16Â Â Â 20 24
c (CFU/100 mL)1600Â Â Â Â 1320Â Â 1000Â Â Â Â 890 650 560
The time is measured in hours following the end of the storm andthe unit CFU is a .colony forming unit.. Use this data toestimate
(a) the concentration at the end of the storm(t = 0) and
(b) the time at which the concentration willreach 200 CFU/100 mL. Note that your choice of model should
be consistent with the fact that negative concentrations areimpossible and that the bacteria concentration always decreaseswith time. Plot the original data and the regression “line†usingMatlab. Submit plot.
