1. For the distribution of ages in Section 1.3.1:
Â
(a) Compute (J2) and (j)2.
(b) Determine ∆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.

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?
Example 1.1
Suppose I drop a rock off a cliff of height h. As it falls. I snap a million photographs, at random intervals. On each picture I measure the distance the rock has fallen. Question: What is the average of all these distance That is to say, what is the time average of the distance traveled?10
