3) Since the estimate of the parameters are given the estimated regression model is:
Now it is given that y19 = – 0.2 and y20 = 0.3
Therefore,
Or,
Thus,
Or,
So, option (e) - 0.254 is the correct one.
4) The estimated regression model is:
Since Jimmy studies on average 11 hours per week so for Jimmy sth = 11 and he drinks on average 4.3 pints of beer a week so awbc = 4.3
Therefore, Jimmy’s predicted grade in ECON20110 is:
So, option (e) 51.24 is the correct one.
help wih these question please 3. Consider the following autoregressive process Yt = Bo + B1yt-1...
1. Consider the following autoregressive process 2+ = 4.0 + 0.8 2t-1 + Ut, where E (u+12+-1, Zt-2, ....) = 0 and Var (ut|2t-1, 2-2, ...) = 0.3. The unconditional E (Zt) and unconditional variance Var (zt) are: (a) E (2+) = 11.1111, Var (zł) = 0.8333 (b) E (2+) = 11.1111, Var (zt) = 1.5 (c) E (zt) = 20, Var (zt) = 0.8333 (d) E (2+) = 4, Var (zł) = 0.8333 (e) E (Zt) = 4,Var (z+)...
