Suppose that we are studying a chemical reaction that generates heat. The following table shows our measurements of the temperature T as a function of time t: t(seconds) 0.5 1.1 1.5 2.1 2.3 T(celsius) 32.0 33.0 34.2 35.1 35.7 It is proposed that the relatition between t and T is described by an equation of the form T = a + b In t. (a) Use the technique of least-squares solutions to nd approximate values of a and b. Round your answer to 2 decimal places
