The “chosen value” is either “odd” or “even.” So either creatures with odd converted mana costs enter the battlefield tapped and creatures with even converted mana costs have haste, or vice versa.

If a creature has X in its mana cost, that X is treated as 0 for the purposes of these effects. It doesn’t matter what the value of X was while the creature was on the stack.
