A.
1.1 (a) <j2>=459.571, <j>2=441,
(b) s=4.309,
(c) <j2>-<j>2=18.571
1.3 (a) A = Ö(l
/ p)
(b) <x> = a,
<x2> = a2
+ 1/(2 l),
s
= (2l)-1/2
1.6 Proof.
B
(a) r(q)
= 1/p, 0<q<
p, and 0 otherwise
(b) See (a)
(c) Proof
(d) <q> = p/2
(e) r(x)
= (1/p)(r2 - x2)
- 1/2, for -r <x< r ; 0 otherwise
(f) <x> = 0, <x2>=r2/2,
s = r/Ö2.
Note that the easiest way to get these is from part (a).
(g) P=2/p
