12 Chapter 1 The Wave Function *Problem 1.1 For the distribution of ages in Section 1.3.1: (a) Compute (./2) and (j)2. (b) Determine Aj for each j, and use Equation 1.11 to compute the standard deviation. (c) Use your results in (a) and (b) to check Equation 1.12. Problem 1.2 (a) Find the standard deviation of the distribution in Example 1.1. (b) What is the probability that a photograph, selected at random, would show a distance x more than one standard deviation away from the average? *Problem 1.3 Consider the gaussian distribution p(x) = Ae-1(x-a)2 where A, a, and A are positive real constants. (Look up any integrals you need.) (a) Use Equation 1.16 to determine A. (b) Find (x), (x2), and o. (c) Sketch the graph of p(x).at 1 = 0, it stays normalized for all future time.
