Problem 1.1 – Griffith’s Intro to QM

Problem 1.1:

For the distribution of ages in the example in Section 1.3.1:
(a) Compute $\langle j^2 \rangle$ and $\langle j \rangle ^2$ .
(b) Determine $\Delta j$ 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.
