Why is replication a good practice in experimental designs?

It allows for chance variation to be estimated.

Which of the following is FALSE about the Central Limit Theorem?

It is only valid if the population distribution is Normal

Choose the best answer.

Claiming all children do not sleep 8 hours when it is true, Claiming all children do not sleep 8 hrs, when they do.

If you toss a fair coin 7 times and get 7 heads, the 8th toss MUST be tails. Is this true?

No. You cannot predict next toss from previous toss.
