Question

What are the properties of a density curve in statistics?

Answer 1

Properties of a density curve would be:

Always positive

and `int_(-oo)^oo f(x) d(x) = 1`

Thus the density function `F(oo) = 1`

unless otherwise restricted.

if `a` is the upper bound for `x` then.

`F(a) = 1`

where `f(x >= a) = 0`
