A chemical engineer is studying the output from a pilot plant for a new chemical process. She would like to model the difference, D, between the output from pilot plant and the current process as a t-random variable with df=2. She has a N(0;1) generator which produces 10 values:
-0.99; -0.84; -0.18; 0.84; -0.52; -0.79; -1:50; -0.44; 0.83; 0.14
Calculate a realization for the difference D.
