a. fit a third-order autoregressive model to the number of passenger cars produced in the united states and test for the significance of the third-order autoregressive parameter (slope). (use a = 0.05.)
b. if necessary, fit a second-order autoregressive model to the number of passenger cars produced in the united states and test for the significance of the second-order autoregressive parameter (slope). (use a = 0.05.)
c. if necessary, fit a first-order autoregressive model to the number of passenger cars produced in the united states and test for the significance of the first-order autoregressive parameter (slope). (use a = 0.05.)
