Let p be an integer other than 0, ±1. (a) Prove that p is prime if and only if it has the property that whenever r and s are integers such that p = rs, then either r = ±1 or s = ±1. (b) Prove that p is prime if and only if it has the property that whenever b and c are integers such that p | bc, then either p | b or p | c.

Suppose that a signal s that takes on values 1 and -1, with probability p and 1-p respectively, is sent from location A. The signal received at location B is Normally distributed with parameters (s, 2). Find the best estimate of the signal sent, in the Maximum Likelihood Estimate sense, if R, the value received at location B, is equal to r.
