Consider an arma process whose ar polynomial is (z)=1 z2/4 and whose ma polynomial is ✓(z) = 1 + z/3. complete the following: • factor the ar and ma polynomials. • determine whether or not (z) and ✓(z) share common factors. • for the arma(p, q) process corresponding to (z) and ✓(z), what are p and q? • is the arma(p, q) process corresponding to (z) and ✓(z) invertible? justify your answer. • is the arma(p, q) process corresponding to (z) and ✓(z) causal? justify your answer.

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5
