False.5% = statistically significant. Look it up. Don't confuse it with p-value.
How about a wager. Why don't you look it up and then post some solid academic evidence that "statistically significant" means "5% of a population". If you can actually find that mythical thing, I'll donate $100 to the forum in your name. If you can't find this mythical thing, all you have to do is admit your error.
