(Where Year = X and Vehicles = Y)
Use logarithms to transform the data into a linear association. White the equation of the LSRL. Your answer should have logs in it. Remember to define any variables.
a. Present a scatter plot for the data. (Hint: let x = 0 represent the year 1940)
b. Determine the correlation coefficient for the data and interpret the value.
