Suppose a $z$-score was calculated and the value was found to be $k$.

Based upon the standard normal distribution, which of the following statements is false?

$p\left( z\ge k \right) >p\left( z > k \right)$.

$p\left( z\ge k \right) =1-p\left( z\le k \right)$.

$p\left( z < k \right) =p\left( z\le k \right)$.

If $k = 0$, the $p(z < k) = 0.50$.

If $k > 0$, then $p\left( z\ge k \right) <0.50$.
