Regression


                          To estimate the constant b, we use the ratios between the sequence terms. We
                                     5
                          know that b  is approximately (56.5/47.5 + 67.2/56.5 + 79.9/67.2)/3=1.18928.
                                                                          1/5
                          Therefore the constant b is approximately b=1.18928 =1.03528. Thus the
                          number of the bacteria in millions is:

                                                      n = 47.7 * 1.03528 m

                          At 11:00, which is 60 minutes later than 10:00, the estimated number of
                          bacteria is:
                                                       60
                          47.7*1.03528 =381.9 7.7*1.03528 =381.9 million.
