Why researchers are interested in describing measures of the center and measures of variation of a data set?
Let Χ be a real-valued character (mod k). Let
k
S = Σnx(n).
n=1
If (a, k) = 1,
ax(a)S = S (mod k).
(iii) Write k = 2ºq where q is odd. Show that there is an integer a
with (a, k) = 1 such that a = 3 (mod 2ª) and a = 2 (mod q).
Deduce that 12S = 0 (mod k).
Solve for 14
