Question

f(x) = (2/81)x for 0 < x < 9;
f(x) = 0 for other

given: M = 6; stand dev. of x = 2.1213

what is E[ |x-M | ] = ?

Answer 1

kinda hard to tell whats being asked...sorry :)

Answer 2

i believe I see an equation for the slope of a line y = (2/81)x for all x in the interval (0,9)

what M=6 means is beyond me; and standard deviation?

Answer 3

E[|x-M|] sounds like an error adjustment or calculation

Answer 4

no
this is probability and statistics question

Answer 5

M is the mean

Answer 6

ahhh....taking that over the summer college :) you got 4 months to wait ;)

Answer 7
