c (CFU/100 mL)1600     1320  1000     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.
