USING MATLAB! USING MATLAB! USING MATLAB! ONLY BY USING MATLAB!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
14.9 The concentration of E. coli bacteria in a swimming area is monitored after a storm:
t (hr) 4 8 12 16 20 24
c (CFU/100 mL) 1600 1320 1000 890 650 560
The time is measured in hours following the end of the storm and the unit CFU is a .colony forming unit.. Use this data to estimate
(a) the concentration at the end of the storm (t = 0) and
(b) the time at which the concentration will reach 200 CFU/100 mL. Note that your choice of model should
be consistent with the fact that negative concentrations are impossible and that the bacteria concentration always decreases with time. Plot the original data and the regression “line” using Matlab. Submit plot.

Find the equation of the regression line for the given data.
Then construct a scatter plot of the data and draw the regression
line. (The pair of variables have a significant correlation.) Then
use the regression equation to predict the value of y for each of
the given x-values, if meaningful. The table below shows the
heights (in feet) and the number of stories of six notable
buildings in a city.
