Not sure who to return the books to, as they are unlabeled, the professor returns the books to the students in a random order. We will first use simulation to investigate what will happen in the long run if this were to happen many times. Simulation Analysis: 1. Tak

From Rex Boggs in Australia comes an unusual data set: before showering in the morning, he weighed the bar of soap in his shower stall. The weight goes down as the soap is used. The data appear in Table II.3 (weights in grams). Notice that Mr. Boggs forgot to weigh the soap on some days. [pic] A. Plot the weight of the bar of soap against day. [pic] [pic] B. Is the overa
