3. Consider the following autoregressive process yr = 50 + 51-1+5₂:-2 + where E (use-1-t-2) = 0. You obtained the following parameter estimates: -0.2, 3₁=0.4 and ₂ = -0.1. Furthermore, you have the following observations: 919 -0.2 and y20 = 0.3. What is the estimate for E (322920-19)? = (a) -0.3333 (b) -0.06 (c) 0.3 (d) -0.2857 (e) -0.254 4. You have estimated the following regression model on the basis of 213 observations: 27.34+ 2.97 sth, - 2.04 awbe (2.64) (0.43) (1.16) 72 = 104, R²0.29 Ə = 3.6, DW = 2.06 where gr is the grade in ECON 20110, sth is the average number of weekly hours spend on studying and awbe is the average weekly beer consumption measured in pints. In parenthesis () you can find the usual standard errors. On average all students study 8 hours and drink 3 pints per week. Jimmy studies on average 11 hours per week and drinks an average of 4.3 pints of beer a week. What is Jimmy's predicted grade in ECON 20110? (a) 28.27 (b) 27.34 (c) 44.98 (d) 54.84 (e) 51.24 3.
