able 2 shows the velocity ( [m/s]) of a cyclist recorded at different times ( [s]) after they started pedalling from a standstill. It has been suggested that the function () = 1 2 may accurately describe the relationship between and . Use this information to complete the following tasks: Table 2 0 1 2 3 4 0.0 0.5 2.0 7.0 14.0 0.0 2.5 4.8 6.5 7.0 a) Use Multiple Linear Regression to compute values of 1 and 2 which give the best fit of () to the recorded data. Plot the fitted curve and datapoints together on an excel chart. (35 5 marks) b) Calculate the coefficient of determination for the fitted curve obtained in (a) (10 marks)
