Suppose you have a system with four levels, Ej (j=0, 1, 2, 3), with energies of (in units of kB·K) 0, 100, 200, 400. Explicitly, if, for example Ej = 100, when T=300, Ej/kT = 1/3.

  1. Determine the average energy of the system by weighted averaging
  2. Determine the average energy by taking the appropriate derivative of ln q.

Suppose you have four classifications: freshmen (f), sophomore (so), junior (j), and senior (se). You construct a dummy variable, one for each classification that takes on the value of (1) should that classification be true for that observation and 0 otherwise. Further assume that you estimate the following model: E[GPA]= .5*ACT+1*So+-0.97*J+{c}*Se How much higher/lower is a Junior's GPA, after controlling for ACT, than for the omitted category?
