(10 points) See the outputs on page S ael- we t two models for simulated time series data Y, against Xi: (a) Write down the tted linear reg-mien. W'hat is the R\" of the linear regrmsicm? Is the tted model adequate? Why? (h) After reviewing the ACF and PACF plots. The researcher decided to t the model 2 with time scrim errors for this simulated data. What is the tted model? Write down the tted model. \"'hat is the residual standard deviation of the model? (c) Based on the available output, is model '2 a good t for the data? Why?
