Which of the following properties is not valid related to probability density function f (x) for normal distribution?
|
If x1 ≤ x2 then F (x1) ≤ F (x2) |
|
∫∞ f(x)dx=1 |
|
The normal distribution function curve is symmetric around the mean, μ. |
|
The probability density function f (x) does not the touch and intersect x axis. |
|
f (x) ≥ 0 for all x values. |
Yanıt Açıklaması:
The property of "If x1 ≤ x2 then F (x1) ≤ F (x2)" is not valid related to probability density function f (x) for normal distribution because it is the property of Cumulative Density Function F(x) of a continuous random variable X.
