. The number of bacteria, n thousand per cm3 , in a sample of liquid is measured over a period of time, t, in hours. The data is shown in the table. t 3.9 5.5 6.8 8.5 10.6 11.5 13.3 14.7 16.5 17.8 n 10. 1 13.1 14.6 20.7 27.9 31.5 40 49.9 64.7 75.6 The data is coded using the changes of variable x = t and y = log10 n. The regression line of y on x is found to be y = 0.7606 + 0.0635x. (a) Given that the data can be modelled by an equation of the form n = abt where a and b are constant...
