The following table shows the world record times for the 200m race for flying start machines (a kind of bicycle). Find the line of best fit model, R(t) , that represents the world record times , t, since 1970. Before determining the equation , we need to convert all years to years since 1970. The first two rows are completed for you . Complete the rest of the table with the correct years since 1970 . After completing the table , use Excel to create a linear regression equation using only the second two columns . Do not use any spaces in your submission .
